Here's what i always get at the store:
Those packs of frozen vegatables, like the Lo Mein, or Chow mein combination. ZERO FAT!!! (ok, one of them has about 1.5 grams fat...)
Then, you take chicken breast (go ahead and get the cheaper, frozen kind, it doesn't take as good, but you are going to cut it up anyways) and put a breast's worth of chicken in the stir fry. Literally takes 7 minutes to make, and its a good amount of protein, and no fat.
My house smells like a chinese restaurant, cause i stir fry so much.
Cottage cheese (lowfat) is great. Want to make it REALLY taste good? Buy some yogurt and put some of that in it. Yogurt is low fat and high protein too.
Protein bars are pretty essential, cause they taste good and easy to pack to work.
I've gotten some cans of turkey chili, and thats only about 3.5 grams fat, but lots o' protein.
Oh yeah, and tuna fish. Goddamn, 32 grams of protein per container for about 45 cents. (dont add lots of fattening mayonnaise though...)
So, those are the things i usually buy. It's a boring diet, but oh well.
