Heat oven to 425°F. Spray cookie sheet with cooking spray; sprinkle with cornmeal. Do not unroll dough. Cut roll of dough into 4 equal pieces; shape each piece into a ball. Roll or press each ball of dough into a 5-inch round making edges slightly thicker to form a rim. Place the rounds on the prepared cookie sheet; brush each with oil.
Bake 6 to 8 minutes. Top each round with 1 of the variations below. Bake 10 to 13 minutes longer or until crust is deep golden brown and cheese is melted and bubbly.
