How to Make It
Preheat broiler to high.
Place a baking sheet in oven; heat for 10 minutes.
While baking sheet heats, place crust on another baking sheet sprinkled with cornmeal. Lightly coat crust with cooking spray. Spread pesto evenly over crust, leaving a 1-inch border; sprinkle mozzarella evenly over pesto. Dollop ricotta, by teaspoonfuls, evenly over mozzarella. Slide crust onto preheated baking sheet, using a spatula as a guide. Broil 5 inches from heat for 5 minutes or until cheese begins to melt. Remove from oven; top evenly with tomatoes, black pepper, and basil. Sprinkle with red pepper, if desired. Cut into 8 slices.
