1Heat gas or charcoal grill. Brush pesto over pizza crust. Sprinkle 1 cup of the mozzarella cheese over pesto. Arrange tomato slices and basil leaves on cheese. Sprinkle with remaining 1 cup mozzarella cheese and the Parmesan cheese.
2Place pizza on grill. Cover grill; cook over medium heat 6 to 8 minutes or until crust is crisp and cheese is melted. (If crust browns too quickly, place a piece of foil between crust and grill.)
