Spinach Calzones Recipe

Cook spinach according to package directions; drain well. In a bowl, combine the spinach, Swiss cheese, ricotta cheese, onion, basil, salt, garlic powder and pepper. Roll pizza dough into a 15-in. x 10-in. rectangle; cut into six 5-in. squares. Spoon 1/3 cup spinach mixture onto the center of each square; brush edges of dough with water. Fold one corner over filling to the opposite corner, forming a triangle. Using a fork, crimp edges to seal. Place in a 15-in. x 10-in. x 1-in. baking pan coated with cooking spray. Prick tops with a fork. Lightly beat egg white and water; brush over dough. Sprinkle with Parmesan cheese. Bake at 425 ° for 10 minutes or until golden brown. Let stand for 5 minutes. Serve with pizza sauce if desired.
