Pizza Calzones

1 (10 oz) can refrigerated pizza crust

6 Tbsp pizza quick sauce

1/4 pound hamburger, browned

1/3 cup chopped onion

1 1/4 cups shredded mozzarella cheese

Heat oven to 425.  Grease cookie sheet.  Unroll dough onto cookie sheet; press dough into a 12x14 inch rectangle.  Cut into 6 equal rectangles.  Spread each piece with 1 Tbsp pizza sauce, to within a half inch of all edges.  Place hamburger on one half of the longest side of each rectangle; top with onion and one cup of cheese.  Starting at longest side, fold dough over to form rectangles.  Seal edges with a fork.  Cut 3 two inch slits in top of each rectangle.  Bake for 9-13 minutes.  Sprinkle with remaining cheese.  Bake 1-2 minutes more.
