Place flatbread on a large baking sheet, and preheat the oven to 425°F.
2 flatbread
Divide the pesto evenly between each flatbread, and spread it into an even layer. Dot the mozzarella cheese among each flatbread, then top with tomatoes.
6 ounce(s) basil pesto, 6 ounce(s) mozzarella, 1 cup cherry tomatoes
Bake the flatbread for 10 to 15 minutes until the cheese melts. Remove from the oven, and drizzle with balsamic glaze. Add the basil leaves and grated Parmesan cheese if desired.
2 Tbsp. balsamic glaze, 8 basil leaves
Cut each flatbread into several pieces, and serve hot. Store leftovers in the refrigerator for up to 3 days.
