03Roll out the dough balls on a lightly floured surface into 4 equal rounds. On half of each round, layer some mozzarella, and then some pepperoni slices. Fold in half, covering the filling, and then fold the outer edges up and crimp the edges with your fingers to seal. Place the pockets on a baking sheet, brush with olive oil and sprinkle with grated Parmesan. Bake until golden, 10 to 15 minutes. Serve with the sauce on the side.
