There's a lot of good ideas from replies to my thread here:

Here's a couple of easy courses for any veggies;
Cube an aubergine, and fry gently in plenty of olive oil until lightly browned, soft and oily.
Add a tin of chick peas, a tin of baked beans, and a tin of chopped tomatoes, and gently stew until you are ready. Add some chilli if you like. Serve with any veg steamed or boiled, or a salad, or just bread, or rice, or even nothing!
My "Quick Camper Crumble";
Stew some fruit with a little sugar - use whatever you can get, or pick - apples, blackberries, gooseberries, any combination (or even tinned peaches etc)
Crumble three or four luxury soft cookies over the top (Stem ginger ones are great)
Pour over ready made custard.
This is delicious. Try it!
