Heat oven to 425°F. Spray 12-inch pizza pan with cooking spray. Unroll dough in pan; starting at center, press out dough to edge of pan to form crust. Bake 7 to 9 minutes or until light golden brown.
Spoon barbecue sauce with pork over crust. Top with cheese, onion and bell pepper.
Bake 10 to 12 minutes longer or until crust is golden brown and cheese is melted.
