Prompt
Act as an expert in household budgeting and efficient grocery shopping.
Context:
- Household: {{household}}
- Weekly grocery budget: {{budget}}
- What I already have in the pantry, fridge and freezer: {{pantry}}
- Meals planned this week (if any): {{meals}}
- Type of store I shop at: {{store}}
- Restrictions or preferences: {{restrictions}}
Deliverables:
1. Pantry check: what to use up first (whatever expires soonest) and what I do not need to buy.
2. If no meals are planned, 5-7 cheap meal ideas that use what I already have.
3. A grocery list sorted by store section, with specific quantities for the household.
4. An estimated cost per item and total, labeling amounts as estimates or [FILL IN] where I cannot know them; if over budget, what to cut or swap.
5. Money-saving tactics that apply: store brands, seasonal produce, frozen options, buying in bulk, comparing unit prices.
6. An anti-waste plan: what to cook first and what to freeze.
Constraints:
- Do not invent real prices for specific stores: treat them as rough estimates and tell me to check them against my receipt or the store's website.
- Respect the dietary restrictions listed and do not sacrifice basic variety (vegetables, fruit, protein) to save money.
- If key information is missing, ask me before writing the list.
Format: a checklist by section, a cost table and a 3-line summary.How to use it
Take a quick look in your fridge and pantry and list the main items in the pantry field. After shopping, paste your receipt into the chat so the next week’s prices are more realistic.
Usage example
Household: 2 adults and 1 child · Budget: $90 · Pantry: rice, canned chickpeas, 6 eggs, spinach about to expire · Store: discount grocery store.
Sample output
1. Pantry check: use first
Yogurt (expires Thursday) for breakfasts and a yogurt sauce for the chicken. Move the half chicken to the fridge Monday to thaw.
2. Meal ideas
- Lentil and carrot stew over rice
- Roast chicken with potatoes and carrots
- Pasta with tomato sauce and vegetables
- Egg fried rice with peas
