Preheat the oven to 375℉. Sauté pancetta in a medium-high heat pan for about 8-10 minutes, until just crispy.
Cut pastry dough into four roughly 8×6” pieces.
Leaving a 1-inch border around all edges of the pastry, added a generous layer of cheese to each. Sprinkle pancetta, splitting evenly between the four tarts.
Add tomato slices, skin down, in a single layer on top of the cheese and pancetta. Sprinkle with the rest of the cheese and shallot rings.
Score the pastry borders with a fork.
Bake for 25 minutes, until tarts are golden brown. Sprinkled torn basil on top of each pastry. Bake for another 5 minutes. Enjoy
Notes
Tarts are best enjoyed right away!
Make them vegetarian by removing the pancetta if desired.
