I'm no gourmet, but I need to eat better.

What I need is a "Menu" of a very limited number of Dishes (I'm thinking 5-10)
That I can:
1. Keep the basic ingredients on hand (preferrably ones that "Keep" well.
2. Make quickly (I don't particularly like to cook)
3. Improve my nutrician by eating (Did you see the moving "Super size me"?)

Nice to haves would be:
1. A mix and match set of ingredients (i.e. 6 things to combine differently to make 10 different meals)
2. Tastes reasonably good and I wouldn't be embarrassed to server to guests.

One book I found that look like the right idea is "A Man, A Can, A Plan"

Any have other resources to use to build that basic "Menu"
