I posted this once before, it is a favourite of mine.

BBQ Chicken Pizza
1 Flat-Out bread (or similar product) I perfer the 1--% whole wheat kind.
2Tbs of Low-Cal Sweet BBQ Sauce
Diced Chicken Breast (from a can or frozen)
1/4 Cup Low-Fat Mozarella Cheese
1/8 Cup Low-Fat cheddar Cheese
2Tbs baccon crumbs

Use the bread as a pizza crust and smear the BBQ sauce all over it.
Heat the chicken any way you wish. I use a skillet but a microwave will do. Placed the diced chicken over the pizza.
Cover in mozarella cheese and cheddar cheese.
Sprinkle baccon crumbs on top.
Bake in a pre-heated oven (300F) for 20 minutes or until cheese is melted.

Has about 300 calories for the whole thing and is full of protien and some fiber.
