Fridge to feast: the Ultron prompt that turns your fridge photo into 16+ meals

Snap one photo of your fridge, hand it to Ultron, and get 16+ meal ideas back, sorted by how long they take and filtered for the way you eat.

Snap one photo of your fridge, hand it to Ultron, and get 16+ meal ideas back, sorted by how long they take and filtered for the way you eat.

No more "what's for dinner" brain freeze. No 7pm takeout spiral. You give Ultron a photo of your open fridge, paste the prompt below, and it reads what you have and turns it into a full meal plan across cuisines, with substitutions and a use-these-first warning for anything about to spoil.

Use it for yourself, or send it to a friend who hates cooking.

How to use this guide

Here is the 4-step flow:

  • Take one clear photo of your open fridge. Pull stuff forward so labels show. Open the crisper drawer too, that is where the forgotten zucchini lives. If you have a separate pantry or spice cabinet, take a second photo. The prompt accepts up to 3 images.
  • Copy the prompt below. The whole thing. Do not trim it, the structure is what makes the output good.
  • Give it to Ultron and attach your fridge photo or photos. Ultron reads images natively.
  • Edit the bracketed bits at the top: your dietary needs, how many people you are feeding, and how much time you have. Then send it.

Ultron replies with 16+ meals across at least 6 cuisines, sorted by cook time, with substitutions, missing-ingredient flags, and a use-these-first warning for anything about to spoil.

Pro tip: if you cook for the same person every week (partner, roommate, kid), save your dietary preferences once at the top of the prompt and just swap the photo each week. Takes 10 seconds.

Prompt
You are my personal AI sous-chef. I am going to give you a photo (or photos) of my fridge, and possibly my pantry, and you are going to turn it into a full meal plan. === MY DETAILS (edit these before you send) === - People I am feeding: 2 - Dietary needs: [pick all that apply: vegan / vegetarian / pescatarian / gluten-free / dairy-free / nut-free / keto / paleo / low-FODMAP / halal / kosher / none] - Allergies / hard nos: [e.g. shellfish, cilantro, mushrooms, no organ meats] - Skill level: [beginner / intermediate / confident home cook] - Equipment I have: [e.g. stovetop, oven, air fryer, rice cooker, blender, microwave] - Cuisines I love: [e.g. Korean, Italian, Thai, leave blank for full variety] - Cuisines to skip: [e.g. no Indian today, had it last night] - Time I have tonight: [5 min / 15 min / 30 min / 45+ min / batch cook for the week] - Spice tolerance: [mild / medium / spicy / max] === STEP 1: READ THE FRIDGE === Look at every photo I have sent. Make THREE lists: 1. CONFIDENT INGREDIENTS: things you can clearly identify, with rough quantity if visible (e.g. half a block of tofu, 3 eggs, ~200g spinach). 2. BEST GUESS: things you think you see but are not 100% sure about. Tell me what you think it is and ask me to confirm. 3. USE FIRST: anything that looks close to spoiling (wilted herbs, browning fruit, opened dairy, leftovers in containers). === STEP 2: GENERATE 16+ MEAL IDEAS === Give me at least 16 meal ideas, organized by COOK TIME. Within each time bucket, give me variety across at least 6 cuisines (rotate through Italian, Chinese, Korean, Japanese, Thai, Vietnamese, Indian, Mexican, Middle Eastern, Mediterranean, French, American comfort, Filipino, Ethiopian, pick what fits the ingredients best). For EACH meal include: - Meal name + cuisine + 1-line description - Total time (prep + cook) - Serves (scale to my people-I-am-feeding number) - Ingredients I have (from the fridge) vs ingredients I would need to buy or substitute - 5-8 step recipe, short, clear, no fluff - Dietary tags (vegan, GF, DF, etc.) - Spice level - One swap tip (e.g. no soy sauce? use tamari + a splash of fish sauce) === TIME BUCKETS (minimum meals per bucket) === - 5-MIN MEALS (no real cooking, assembly only): at least 3 - 15-MIN MEALS (one pan, fast): at least 4 - 30-MIN MEALS (proper dinner energy): at least 5 - 45+ MIN MEALS (slow build, weekend vibes): at least 2 - BATCH COOK (1 cook, 3+ meals): at least 2 === STEP 3: BONUS LAYER === After the 16 meals, give me: - SHOPPING SHORTLIST: top 5 ingredients to buy that would unlock the most additional meals from what I already have - LEFTOVERS REMIX: for the 30-min and batch-cook meals, suggest how to turn leftovers into a different meal tomorrow - SIDES AND SAUCES: quick sauces, dressings and dips I can make from what is in the fridge (chimichurri, gochujang mayo, tahini-lemon, etc.) - WHAT NOT TO COOK: meals to skip given what I have, so I do not waste mental energy considering them === FORMATTING === - Use clear headers so this is scannable on my phone - Group meals by time bucket, then cuisine - Bold the meal names - Keep recipe steps under 8 lines each - End with the shortlist + leftovers + sauces + skip list - Do not add disclaimers, just give me the food Ready? Here is my fridge. [attach 1-3 photos]

Dietary preset cheat sheet

Pick the line that matches you and paste it into the Dietary needs field. You can stack them, "vegan + gluten-free" works fine.

  • Vegan: watch for hidden dairy in pesto, and fish sauce in Thai and Vietnamese dishes.
  • Vegetarian: watch for anchovies in Caesar, and gelatine in some yoghurts.
  • Pescatarian: watch for chicken stock in soups.
  • Gluten-free: watch for soy sauce (use tamari), couscous, and miso.
  • Dairy-free: watch for butter in pan sauces, and cream in curries.
  • Keto or low-carb: cap around 20g carbs per meal, watch for hidden sugar in marinades and sauces.
  • Nut-free (including peanuts): watch for pesto, satay, and many Asian sauces.
  • Low-FODMAP: no garlic or onion; almost every recipe will need swaps.
  • Halal: no pork, no alcohol in cooking; watch for mirin and wine reductions.
  • Kosher: no pork or shellfish, no mixing meat and dairy; watch cheese on burgers and cream sauces with chicken.

Time bucket cheat sheet: what to expect

  • 5-min meals = assembly only. Wraps, toasts, salads, smoothie bowls, no-cook noodle bowls.
  • 15-min meals = one pan, high heat, done. Stir-fries, fried rice, omelettes, quesadillas, pasta aglio e olio.
  • 30-min meals = proper dinner. Sheet-pan everything, curries, pad see ew, gnocchi, tacos.
  • 45+ min meals = lazy Sunday energy. Braises, roasts, ramen broth, stews, biryani.
  • Batch cook = one cook session, 3+ meals out of it. A big pot of bolognese becomes pasta night, lasagne, and jacket potatoes. Roast chicken becomes tacos, soup, and a sandwich.

Cuisine variety: what 16 meals can look like

Here is a sample of what Ultron might generate from a normal fridge (eggs, tofu, spinach, carrots, half an onion, leftover rice, soy sauce, cheese, tortillas, sad herbs, lemon):

  • 5-min: avocado-egg toast (American), Vietnamese herb wrap, Greek-style yoghurt bowl
  • 15-min: Korean kimchi fried rice, Italian cacio e pepe, Thai basil tofu, Mexican egg quesadilla
  • 30-min: Japanese tamago-don, Indian palak tofu, Middle Eastern shakshuka, French frittata, Chinese tomato-egg stir-fry
  • 45+ min: Italian baked ziti, Korean kimchi jjigae
  • Batch cook: Mediterranean grain bowl base (cooks once, eats 4 ways), Thai red curry sauce (freezes, deploys all week)

That is 16 meals from 11 cuisines, all from the same fridge.

Pro tips to get better outputs

  • Take the photo in good light. Phone flash works. Ultron cannot identify what it cannot see.
  • Pull stuff forward. The yoghurt at the back of the second shelf is hiding three meals.
  • Mention what you ate yesterday. Add "I had Thai last night" and Ultron will rotate cuisines so you do not repeat.
  • Be honest about skill level. Put "beginner" and it skips knife-skill-heavy stuff. Put "confident" and it will suggest braises and laminated dough.
  • Mention freezer items in text. Ultron cannot see your freezer through the door, so type "also in freezer: frozen prawns, peas, puff pastry" to unlock more meals.
  • Ask for follow-ups. Once you pick a meal, paste the recipe back and ask "walk me through this step by step like I have never cooked it before" or "scale this to 4 people".

Troubleshooting

  • "It missed half my ingredients." Take a second photo from a different angle, or list the ones it missed in text. Stacked items are hard to read.
  • "All the meals need stuff I do not have." Re-prompt with "redo this using ONLY ingredients you can confirm from the photo, no shopping required".
  • "The ideas feel boring." Add "surprise me, lean into less-common cuisines like Filipino, Ethiopian, Peruvian, Georgian" to the Cuisines I love field.
  • "Too spicy or not spicy enough." Adjust the Spice tolerance field. "Max" pulls out the sambal, gochugaru and chili crisp. "Mild" keeps things gentle.
  • "Took longer than the estimate." Add "add 10 min to every estimate, I am slow with a knife" next time.

Run this on autopilot.

Everything in this guide becomes an agent inside Ultron: set it up once, keep it running. You review, it executes.
