Heat oven to 375°F. In 8-inch skillet, cook sausage, onion and bell pepper over medium heat 10 minutes, stirring frequently, until sausage is no longer pink; drain. Cool 10 minutes.
Separate dough into 5 biscuits. On ungreased large cookie sheet, press each biscuit into 6-inch round. Top half of each round with sausage mixture and cheese to within 1/2 inch of edge. Fold dough over filling; press edges firmly with fork to seal.
Bake 12 to 15 minutes or until golden brown. Serve warm calzones with warm pasta sauce for dipping.
