One batch frozen pizza dough
2 cups ricotta cheese
1 cup chopped/grated Mozzarella
1 cup grated Parmesan
Salt and pepper
Your choice of filling ingredients: 1 chopped onion, 1/2 cup chopped red pepper, 1 cup sliced mushrooms or 1 cup chopped cooked spinach.
Knead your dough on a floured surface for a few seconds, divide it into two pieces, form them into balls, and let them rest for 20 minutes under a towel.
Preheat your oven to 350. Drain your ricotta in a fine mesh strainer (or paper towel lined colander) for 10 minutes. Prepare the filling ingredients if pre-cooking is needed (i.e. saute the onion and pepper). Mix the three cheeses and your filling of choice ingredients in a bowl. Add salt and pepper to taste. Roll out your dough balls into 8 – 10″ circles with an even thickness. Letting them rest for a few minutes after first rolling them out will make it easier. Transfer the rounds to a piece of parchment paper. Add half the filling to each piece of dough. Maneuver the filling onto half of the dough, moisten the edges of each round with water, and then fold over the empty half of dough to enclose the filling. Press the edges closed. Bake the calzones on a cooking sheet or baking stone for 30 to 40 minutes until golden. Makes 2. Serves 4.
