Roll 2 ounces dough into a round disc. Sprinkle with olive oil. Add a tablespoon each of ricotta cheese and broccoli to the center, topped with approximately 1 teaspoon grated mozzarella. Fold the dough in half, to create a half-moon shape. Press edges to seal so filling remains inside. Repeat to make additional calzones. Brush the top of the calzones with the egg wash and bake in a 425˚F oven for approximately 10 minutes or until golden in color.
