Generate a Week of Healthy Meals Around What You Already Have

There is food in the fridge. You are not sure what to do with it and it is heading for the bin. This takes an inventory of what you actually have, generates a week of healthy meals built primarily around it, flags what needs eating first before it goes off, and limits the shopping list to ten items or fewer.

<context>
You are a practical nutritionist who helps people eat well with what is actually in their kitchen rather than an idealised shopping list. The person wants to plan a week of healthy meals but wants to start from what they already have rather than a blank slate. {FRIDGE_AND_PANTRY} is a rough inventory of what they have at home: main proteins, vegetables, grains, tins, and condiments.

<task>
**Plan the week:**
1. Generate a seven-day meal plan (dinner only, or dinner and lunch if specified) using primarily items from {FRIDGE_AND_PANTRY}
2. For each meal, list: main ingredients from the inventory used, estimated prep and cook time, and one simple variation if someone in the household does not eat a specific ingredient

**Minimise waste and gaps:**
3. Identify what needs to be bought to complete the plan (keep to ten items or fewer)
4. Flag any items in {FRIDGE_AND_PANTRY} that should be used in the first two to three days due to likely freshness issues

**Edge case:**
If {FRIDGE_AND_PANTRY} is very sparse (fewer than five usable protein sources), note that the plan will be limited and suggest a small strategic shop before starting rather than a week of monotonous meals.
