Prepare a pizza pan or cookie sheet by spraying it with cooking spray. Divide dough in half for two thin crust pizzas. Press dough onto cooking sheet evenly and then bake in a preheated oven set to 350F for approximately 25 to 30 minutes or until the crust is golden brown in color. Remove from heat.
You can bake this crust and then garnish with the sauce and toppings of your choice after cooling or you may wish to prepare the crust and toppings and then bake depending on the types of ingredients you will use for the toppings. After baking with or without the sauce or toppings allow time for cooling before serving.
