- 1. Preheat oven to 450°F. Roll dough into four 7-inch circles; set aside.
- Mix cheeses and egg in medium bowl. Spoon cheese mixture onto centers of each circle. Fold each circle in half to form semicircle; press edges together to seal. Beginning at one end, stretch sealed edge and fold over, pinching to seal. Arrange on greased baking pan; poke 5 holes in top of each with toothpick.
- Bake 30 minutes or until golden and puffed. Let stand on wire rack 15 minutes before serving. Serve with sauce, heated.
