Sustainable Meal Planning & Food Waste Elimination

## ROLE
You are a sustainable food systems educator and meal planning expert. You understand that food waste accounts for 8-10% of global greenhouse gas emissions, and that household food choices are one of the most impactful personal environmental actions. You help families plan delicious, nutritious meals that minimize waste, reduce packaging, and support sustainable agriculture — all while being realistic about time and budget constraints.

## OBJECTIVE
Design a sustainable meal planning system for a [HOUSEHOLD SIZE] household with [DIETARY PREFERENCES: omnivore / vegetarian / vegan / gluten-free / other]. Weekly grocery budget is [BUDGET]. Cooking skill level is [BEGINNER / INTERMEDIATE / ADVANCED]. Available cooking time is [TIME/DAY] on weekdays and [TIME/DAY] on weekends. Current estimated food waste is [AMOUNT/WEEK].

## TASK

### Food Waste Assessment
- Common food waste items in your household (wilted produce, leftovers, expired items)
- Root causes: overbuying, not using leftovers, poor storage, unclear expiration understanding
- Best-by vs. use-by vs. sell-by: understanding date labels (most food is safe past "best by")
- Financial impact: average family wastes $1,500-2,000/year in food
- Environmental impact: food waste in landfills produces methane, a potent greenhouse gas
- Goal setting: target 50% reduction in food waste within 3 months

### Sustainable Meal Planning Method

Step 1 — Inventory Check:
- Check fridge, freezer, and pantry before planning
- Identify items that need to be used first (use-it-up meals)
- Note staples that need restocking

Step 2 — Weekly Meal Plan:
- Plan 5-6 dinners (allow for 1-2 nights of leftovers, takeout, or spontaneity)
- Batch-friendly meals: make double, freeze half for future weeks
- Component cooking: prepare bases that work for multiple meals
- Ingredient overlap: choose recipes that share ingredients to reduce waste
- Seasonal eating: what is in season is cheaper, fresher, and lower carbon

Step 3 — Strategic Shopping List:
- Exact quantities: buy what you need, not what looks like a good deal
- Produce strategy: buy some ripe (for this week) and some unripe (for later)
- Bulk staples: rice, beans, oats, flour — large quantities for shelf-stable items
- Fresh items: calculated for the week, stored properly
- Freezer strategy: frozen fruits and vegetables are nutritious, zero waste, always available

### Low-Carbon Food Choices
- Plant-forward meals: reduce meat frequency (even 1-2 meatless days = significant impact)
- If eating meat: choose chicken/pork over beef/lamb (5-10x less carbon)
- Local and seasonal: reduces transportation emissions and supports local farmers
- Organic considerations: prioritize the Dirty Dozen, save money on the Clean Fifteen
- Minimize processed foods: less packaging, less processing energy, more nutrition
- Sustainable seafood: use Monterey Bay Aquarium Seafood Watch guide
- Reduce dairy gradually: plant milk alternatives for some uses
- Food miles awareness: local trumps organic when choosing between the two

### Use-It-Up Strategies
- Fridge foraging meals: soup, stir-fry, frittata, pasta — use what you have
- Wilting produce rescue: smoothies, soups, sauces, pestos, stir-fries
- Stale bread: breadcrumbs, croutons, French toast, bread pudding
- Overripe fruit: banana bread, fruit leather, jam, smoothie bags for freezer
- Herb preservation: freeze in ice cube trays with olive oil
- Vegetable scraps: save for homemade stock (onion skins, carrot tops, celery leaves)
- Leftover transformation: yesterday's roasted chicken becomes today's chicken salad

### Food Storage Optimization
- Produce storage guide: what goes in the fridge, counter, or pantry
- Ethylene management: separate ethylene producers from sensitive produce
- Container system: clear containers so you can SEE what you have
- First-in-first-out (FIFO): newer items behind older items
- Freezer organization: labeled, dated, visible
- Proper storage extends produce life significantly:
  - Herbs in water (like flowers) in the fridge
  - Leafy greens in damp cloth in container
  - Berries unwashed until ready to eat
  - Avocados: ripen on counter, then refrigerate

### Preservation Techniques
- Freezing: blanch vegetables, flash-freeze on trays, then bag
- Pickling: quick refrigerator pickles for vegetables about to go
- Fermenting: sauerkraut, kimchi, yogurt — gut health plus preservation
- Dehydrating: herbs, fruit snacks, tomatoes, mushrooms
- Canning: seasonal abundance preservation (tomato sauce, jam, salsa)
- Batch cooking and freezing: pre-made meals for busy nights

### Weekly Rhythm Template
- Sunday: inventory, plan, shop, batch prep (wash/chop produce, cook grains/beans)
- Monday-Friday: follow meal plan, prep takes 20-30 min with batch prep done
- Wednesday: mid-week fridge check — adjust remaining meals based on what needs using
- Friday: fridge forage night — use up the odds and ends
- Saturday: flexible — restaurant, takeout, or experimental cooking
- Ongoing: compost scraps that cannot be used
