Step 1

Heat oven to 425°F. Spray cookie sheet with cooking spray; sprinkle with cornmeal. Unroll dough; place on cookie sheet. Starting at center, press out dough into 14x12-inch rectangle. Brush dough with olive oil.

Step 2

Bake 6 to 8 minutes. Sprinkle Cheddar cheese in the shape of a "plus sign" on crust, dividing the crust into four squares. Top each square with 1 of the 4 variations listed above to make 4 different squares; if desired, on the Pepperoni Pizza Square, arrange the pepperoni to make a happy face. Top entire pizza with mozzarella cheese.

Step 3

Bake 10 to 13 minutes longer or until crust is deep golden brown and cheese is melted and bubbly. Cut pizza into 4 squares; cut each square into 4 squares to make a total of 16 squares.
