Grilled Bbq Chicken Pizza

Cook chicken in 1/2 cup barbecue sauce until no longer pink and set aside. Spray work surface lightly with nonstick cooking spray. Combine rolls together and roll into a 13 inch circle. Place on a sprayed 12inch pizza pan, building up edges slightly. Poke crust several times with a fork to prevent bubbles from forming. Grill, covered, over medium heat for 10-15 minutes. Remove from grill. Spread with remaining barbecue sauce. Top with chicken mixture, peppers, mushrooms and tomato. Sprinkle with cheese. Grill, covered, 5-10 minutes longer or until crust is golden and cheese has melted.
