What you’ll learn
The problem: Planning dinners and remembering what to buy can take time, especially when ingredients are used in more than one meal.
How AI can help: AI can combine ingredients and organize a grocery list around food you already have. You still need to check the amounts, your preferences, and any allergies.
In this lesson: You’ll practice making and checking a shopping list for three made-up dinners.
What you’ll need: A phone, tablet, or computer with internet access and an AI chat. We’ll use ChatGPT as an example.
Before you start: Use the made-up example below. Don’t share passwords, account numbers, or sensitive personal or work information.
1. Open an AI chat
Open ChatGPT (opens in a new tab) or another AI chat you already use. If you’re new to AI chat, start with your first conversation with AI. If asked to sign in or create an account, follow the instructions. A free option is available; access and limits can vary.
2. Try the example
Copy or type the full example below into the message box and send it. The ingredients and pantry amounts are made up for practice.
Your first message:
Make a grocery list for these three fictional dinners. Dinner 1 uses 1/2 cup dry rice, 1 can of beans, and 1 bell pepper. Dinner 2 uses 4 eggs, 1 bell pepper, and 2 cups of spinach. Dinner 3 uses 1/2 cup dry rice, 1 can of beans, and 2 cups of spinach. I already have 1/2 cup dry rice, 1 can of beans, and 2 eggs. Combine the ingredients and subtract what I have. Show the amount still needed; do not guess package sizes.
Need help copying and pasting?
On a computer: Select the message above. Copy with Ctrl+C on Windows or Command+C on a Mac. Switch to the AI chat tab, click the message box, and paste with Ctrl+V or Command+V.
On a phone or tablet: Touch and hold the message, adjust the selection handles if needed, and choose Copy. Switch to the AI chat tab, touch and hold the message box, and choose Paste.
If the button doesn’t work, use these steps or type the message yourself. Remember to send it.
3. Ask for a change
In the same conversation, send this follow-up to make the list easier to use:
Your follow-up message:
Please organize the remaining ingredients into produce and other groceries. Keep the amounts the same, and show rice as dry rice.
What a helpful answer might look like
This is an example we wrote for the lesson, not a recorded AI response. Your answer may use different words or ideas.
- Produce: 2 bell peppers and 4 cups of spinach.
- Other groceries: 1/2 cup dry rice, 1 can of beans, and 2 eggs.
The list shows the amount needed, not a claim that stores sell those exact package sizes. Choose the packages that work for you.
4. Check the answer
Look at the reply you received and ask yourself:
- Did AI combine ingredients used in more than one meal?
- Did it subtract the pantry items only once?
- Are the rice amounts shown as dry rice?
The three dinners use 1 cup of dry rice, 2 cans of beans, 2 peppers, 4 eggs, and 4 cups of spinach. After subtracting the stated pantry items, the remaining amounts match the list above.
Try it with your own idea
Ask AI to suggest a few simple dinners for the number of people you’re feeding. Tell it about your time, preferences, and any ingredients you want to use. Choose the meals you like, then ask for ingredients and a combined shopping list that subtracts what you already have. Check quantities, allergies, safe cooking, and your budget yourself.
What if I get stuck?
The list includes food I already have. Tell AI the pantry amount again and ask it to show the subtraction.
I don’t like an ingredient. Ask for an alternative that fits your preferences, then check the revised list.
This exercise is for meal organization, not personalized medical or dietary advice.
You’ve finished when: You’ve tried the example, asked for a change, and checked whether the answer fits the facts you supplied.
