Outcome
Cooking for a household with mixed needs (no red meat for one, extra protein for another, a baby, and occasional guests), Fei Jiang used GPT and Codex to build a 'Meal Prep OS'. It reads a fridge photo to see what's there and what should be used soon, builds a weekly plan with reused ingredients and a prep sequence, makes one consolidated grocery list to paste into a delivery app, and estimates nutrition and cost per meal and serving.

The source didn't share its exact prompt, so we wrote this from what it describes.
Let's work this out together. I'll tell you what I know, you suggest options and ask what you need, and we'll narrow it down step by step. Nothing gets booked, bought or sent until I say so. Goal: Help me plan a week of meals for a household where people have different needs, using what's already in the fridge first. What I'll share as we go: - Who's eating and their needs (diets, protein goals, a baby, guests) - A photo of the fridge and pantry - Nights I have less time to cook - Rough weekly food budget Rules: - Start from what's already there and what needs using soon. - Reuse ingredients across meals and give me a prep order so I don't repeat work. - Make one combined grocery list grouped by aisle. - Label nutrition and cost figures as estimates. - Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify. Output: A weekly plan, a prep sequence, one grocery list, and estimated nutrition and cost per meal. You'll know it worked when: everyone's needs are covered, less food is wasted, and I can see what we spend per meal.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.

When Brooke Ferrier, a parent of two on the NSW Central Coast, and their partner both lost their jobs, Ferrier asked ChatGPT for a low-cost meal plan for two adults and two toddlers, then refined it with follow-ups: hidden vegetables, low-carb options and no lentils. ChatGPT gave one recipe per meal with variations for each person, compared supermarket prices and produced a categorised shopping list with quantities. A week of breakfasts, dinners and snacks came to $140, against the $400–$500 Ferrier had been spending every four or five days, with much less food thrown out. Ferrier also uses it to find recipes for long-forgotten pantry items.
