Prepare the Puff Pastry: Roll out the puff pastry onto the prepared baking sheet. Prick it all over with a fork to prevent excessive puffing during baking.

Spread the Pesto: Use a spoon to spread the basil pesto evenly across the surface of the puff pastry, leaving a small border around the edges.

Layer the Toppings: Arrange slices of tomato and fresh mozzarella in an alternating pattern on top of the pesto layer.

Season and Drizzle: Lightly drizzle olive oil over the toppings. Add salt and black pepper to taste if desired.

Bake: Place the puff pastry in the oven and bake for 18-20 minutes, or until the edges are golden brown and crispy.

Finish with Basil: Remove from the oven and let cool for a few minutes. Garnish with fresh basil leaves and serve warm
