Preheat grill to high. Spray the grill with non stick grilling spray.
Grease a baking sheet with olive oil. Unroll the refrigerated pizza dough and divide into 2 pieces. Flatten and shape the dough on the prepared baking sheet. (Don't build the dough up around the edges.)
Once the grill is hot, slide the pizza dough onto the grill. Grill, covered, for 2 minutes or until the dough is starting to brown. Watch carefully so it doesn't burn. Turn the dough over and repeat on the other side.
Remove the pizza crusts from the grill. Reduce heat to medium. Top with pizza sauce, some cheese and your choice of toppings. (Don't weigh the pizza down with too many toppings.) Grill, covered for an additional 2 to 3 minutes or until cheese is melted.
