Roll out refrigerated pizza dough to 1/4-inch thick; cut into 3-inch rounds. Top with tomato sauce and grated mozzarella and parmesan. Brush the edges with beaten egg, fold in half and press to seal. Brush with egg and sprinkle with parmesan before baking. Poke a hole in each; bake 20 minutes at 400 degrees F.
