I am an expert at this (or, at least I like to think so). I try to make tasty nutritional meals with variety (as much variety as possible on my budget anyway)
1) Pasta with tomatoes, basil a little sweet vinegar
2) Rice stil fry with been sprouts and sweet chilli sauce
3) Baked potato with cheese and spring onions
4) Omlette made with bean sprouts, spring onion, two eggs, tomatoes, milk
5) Toast and egg (various methods)
6) Banana fritter, old bananas (very cheap) fried in a pan with flour, egg, suger and some chololate powder
...I guess I need to think of a few more...
