In large skillet, over medium-high heat, cook beef, onion, pepper and garlic until beef is no longer pink, stirring to break up meat; drain. Keep warm.

In small skillet, over medium heat, heat tomato sauce, steak sauce and Italian seasoning to a boil. Reduce heat to low; simmer 5 minutes or until slightly thickened. Stir 1 cup tomato sauce mixture into beef mixture; set aside. Keep remaining tomato sauce mixture warm.

Unroll pizza dough from 1 package; divide into 4 equal pieces. Roll each piece into a 6 inch square; spoon 1/3 cup reserved beef mixture onto center of each square. Top with 1/4 cup cheese. Fold dough over to form triangle. Press edges together, sealing well with tines of fork. Place on lightly greased baking sheets. Repeat with remaining dough, filling and cheese to make a total of 8 calzones. Bake at 400 for 20 minutes or until golden brown. Serve with warm sauce. Garnish as desired. Makes 8 servings.
