Italian Pizza Calzones

1/2 pound Italian sausage

26 ounces Beef pasta sauce

1 cup Fresh mushrooms -- sliced

1/2 cup Green pepper -- chopped

1/2 cup Onion -- chopped

2 packages Refrigerated crescent rolls

1 Egg -- beaten

1 tablespoon Water

1 cup Mozzarella cheese -- shredded

Preheat oven to 350 F. In large skillet, brown sausage, pour off fat. Add 3/4 cup pasta sauce, mushrooms, green pepper and onion. Simmer uncovered for 10 minutes. Meanwhile, unroll crescent dough and separate into 8 rectangles. Firmly press perforations together and flatten slightly. In a small bowl mix egg and water, brush on dough edges. Stir cheese into meat mixture. Spoon equal amounts of meat mixture onto half of each rectangle to within 1/2 inch of edges. Fold dough over filling. Press to seal edges. Arrange on baking sheet; brush with egg mixture. Bake 15 minutes or until golden brown. Heat remaining pasta sauce; serve with calzones. Refrigerate leftovers.
