Dredge each pizza dough ball into 1 cup of cornmeal and stretch to a 12-inch circle.
Transfer to a greased pizza pan with holes. Spread 1 cup of tomato sauce over the top leaving a 1-inch border for the crust. Top with your favorite toppings or make a specialty pizza.
Bake on the bottom rack of a 500°F oven for 10-12 minutes or until the crust is dark brown. Slice into 8 slices and serve.
