fry up a pound of burger, or ground chicken/turkey, and drain fat.
toss in a can of stewed tomato/jalapeno and cook it down so its not so runny.
take a whole wheat tortilla and warm it, and smear low fat sour cream on half if it, then put some meet mixutre on that, add sliced black olives and put lots of chopped up iceburg lettuce and fold over. lay sliced tomato on top and its yummy.
Notice I didn't add cheeze, if you can't live without cheeze of course you can add that. I just feel that cheeze doesn't add enough flavor to justify the extra cals. but you can add chopped up green onion, or pepers, or what ever you like.
