Cherry Tomato and Cheese Puff Pastry Tart

Thaw the frozen puff pastry by either putting it in the fridge overnight or laying it out on the counter, wrapped, for about 30 minutes. Preheat the oven to 400 degrees.

Meanwhile, place cherry tomatoes in a big bowl and toss with some olive oil, salt, pepper.

Place a sheet of parchment paper on a baking pan.

Place the thawed puff pastry on a lightly floured counter. Unfold the flaps. Lay a sheet of plastic wrap on top of the pastry and, with a rolling pin, just slightly roll the dough so the seams are not so prominent. Transfer the dough to the baking sheet.

With a very sharp small knife, score the puff pastry all along the sides about 1/2 inch, to just make a small border. Inside the border, dock the pastry with a fork. Very thinly spread the mustard on the pastry. Sprinkle the cheeses on the mustard and top with the tomatoes, stems side up for tomatoes with stems (for decoration).
