I think you will send yourself mad trying to cover all bases.
People will have to bring stuff. Get everyone to bring things and order a simple main food shop.
Tell everyone to bring their own breakfast faves.
Get people to bring the tea and coffee / drinks they like.
One person sort the household stuff so you don't have tonnes of foil, washing liquid, soap, kitchen roll etc. Dont need tk buy it all afresh for a week.
Keep breakfast simple. Maybe 1 of 2 fry ups but mainly cereals/ toast/ jam.
Lunches simple too.
Lots of sarnie stuff.
youll need loads of bread and milk
Cooking all those meals is a bind.
Make one of your meals really easy like pizza.
Another meal of soup with part baked rolls and nice dessert.
Curry and chilli are good calls. Rice naan mango chutney samosa or onion bahjiis all great with the curry, with the chilli lots of cheese (pre grated) and sour cream, do nachos with guacamole.
Tell people to bring some food they like for lunches and treats (not everyone will,).
Make one meal a using everything up leftovers meal
An a couple of pub meals or takeaway. Done!
