How can AI help me meal prep lunches for work?

Tell ChatGPT or Claude how many lunches you need, your budget, diet and whether you can reheat at work, then ask for recipes, a shopping list and a single cooking order for a batch session. Follow official food-safety advice on how long cooked food keeps.

Copy-and-paste prompt

Swap the bits in [square brackets] for your own details.

Plan 5 work lunches I can batch-cook on [day] in under [time]. I have [fridge/microwave at work or not]. Diet: [needs]. Budget: [amount and currency]. Give me: the recipes, a shopping list, a step-by-step cooking order to do them all at once, and how long each keeps in the fridge.

How to do it

  1. Open ChatGPT or Claude and start a new chat.
  2. Copy the prompt below and replace everything in [square brackets] with your details.
  3. Read the answer and ask follow-up questions to adjust it.
  4. Check anything important yourself, then save or print the result.

What a good answer looks like

Illustrative example written by the AI My Day team to show the kind of answer you can expect. Real results vary.

Batch session (Sunday, about 90 min) 1. Oven on: roast a tray of peppers, courgette and chickpeas (35 min). 2. Meanwhile cook 300g bulgur wheat. 3. Make a lemon-yoghurt dressing. Lunches: Mon/Tue – roast veg & bulgur salad; Wed/Thu – chickpea & spinach wraps; Fri – leftovers bowl. Keeps: most cooked dishes are best eaten within a few days – check food-safety guidance and freeze Thursday's portion if unsure.
