What are some easy, inexpensive low-carb recipes?

Buy some whole wheat pita bread, the kind that is not cut in half. Brown some lean ground beef and drain it well. Spread some fat free spaghetti sauce on your pita bread. Put some of the ground beef on it and whatever other toppings you like on a “pitza”. Top with fat free or low fat mozzerella cheese. Bake in a 400 degree oven til cheese is melted and the pita is just starting to get crisp.
I have 2 daughters and when we make this, I put a variety of toppings, such as green peppers, onions, mushrooms, jalapenos, etc., in bowls and let everyone make their own to their liking. We also use chicken breast instead of ground beef sometimes. Use your imagination and see what you come up with.
