CHEESEBURGER PIZZA

2 (10 oz.) tubes refrigerated pizza dough
1 lb. ground beef
1 can or jar of pizza sauce
2 tsp. prepared mustard
1/8 tsp. pepper
1 large onion, thinly sliced
1 lb. American cheese slices

Preheat the oven to 425 degrees.

Grease two 12 inch pizza pans or two 13x9x2 inch baking pans (cookie sheets).

With lightly greased fingers, push the dough into a circle for round pans or as close to the corners as possible on the baking pans. Build up edges slighlty. Place in the oven for about 10 minutes or until lightly browned.

Meanwhile, cook ground beef in a large skillet until browned and drain off the fat. Stir in the pizza sauce, mustard, and pepper and bring to a boil. Reduce the heat and simmer, uncovered, for about 5 minutes.

Spread meat mixture evenly over crusts. Top with onion and cheese slices. Bake 10 to 15 minutes longer or until cheese is melted and pizza is heated through. Remove from oven and let sit for 5 minutes before cutting.
