Heat grill. Lightly grease 12-inch pizza pan or 13x9-inch pan. Unroll dough; place in greased pan. Starting at center, press out dough with hands.
When ready to grill, place pan on gas grill over medium heat or on charcoal grill 4 to 6 inches from medium coals. Cook 5 minutes or just until crust begins to brown.
Remove pan from grill. Spread tomato sauce evenly over partially baked crust. Arrange vegetables over sauce. Sprinkle with cheese. Return pizza to grill; cook an additional 10 minutes or until crust is deep golden brown and cheese is melted.
