PREPARE Easy Basic Meatballs as directed, except use 1 lb. each extra-lean ground beef and ground pork, shape the meat mixture into 24 (2-inch) meatballs and increase the baking time to 15 min. or until meatballs are done (160ºF).
HEAT oven to 400ºF. Unroll 1 pizza crust; press lightly onto bottom of 13x9-inch pan sprayed with cooking spray; spread with half the pizza sauce. Top with meatballs, arranging in 4 rows of 6 meatballs each. Cover with remaining sauce; top with peppers, shredded cheese and Parmesan.
UNROLL remaining pizza dough; place over pizza. Pierce with large fork at 2-1/2-inch intervals to allow steam to escape.
BAKE 20 min. or until golden brown.
