Its hard to find a single item of food that is high fiber/protein without having a ton of carbs also. So I usually split them up: for fiber very low cal veggies like green beans, brocoli, red and green peppars, onions, celery and carrots (I belive these are "free" foods on weights watchers) and then for my protein I try to eat a pure protein food like healthy choice meats, chicken breast, tuna packed in water, shrimp, other seafood. I also like low fat dairy for protein. It has some lactose carbs but they don't seem to affect me like grain/bean carbs in terms of weight gain.
