This is my version of BBQ Chicken Pizza that I came up with after watching an episode of Sandra Lee's Semi-Homemade. I made some adjustments to accommodate a Weight-Watcher's eating plan and I think it came out pretty well.
Preheat oven to 425 degrees. Chop or pull apart chicken. Add enough bbq sauce to just coat the chicken - 2-3 tablespoons.
Place crusts on baking sheets or pizza pans. Spread bbq sauce over each crust to within 1-inch of the edge - use maybe 1/4 cup per crust (more or less to your preference).
Place 1/2 the chicken on each crust, spreading out to evenly cover the sauce. Cover the chicken with mozzarella and cheddar, dividing evenly between the 2 pies. Divide the bacon and sliced onion evenly between the 2 pies.
Bake for about 10 minutes until the cheese melts and the bacon starts to brown. Check the bottom of the crust to make sure it's not burning. If it looks like the crust will burn before the bacon crisps enough, turn on the broiler to finish browning the top. Cut into wedges and serve.
