Toss tomatoes with oil, salt and pepper. Set aside.
Unroll puff pastry on baking sheet lined with parchment paper and cut into 9 squares. Roll in edges of puff pastry slightly to create a frame. Top each square with 1 tsp. pesto, feta and a tomato slice.
Bake 20 minutes, or until lightly browned.
Remove from oven and top with fresh basil.
