This simple pizza tastes great as it is, but you can jazz it up with any of your favorite toppings.
1. Brush grill grate well with oil, and preheat grill to medium.
2. Spread pesto over crust. Top with tomato slices, mozzarella, and basil. Place pizza on grill, close lid, and grill 5 minutes, or until cheese has melted. Sprinkle with Parmesan, if using.
