In a medium skillet over medium heat, melt the butter and stir in Worcestershire sauce, hot sauce and tomato sauce.
Remove the chicken from grill and thinly slice it. Add the chicken to sauce and coat. Cover the pizza dough with the saucy Buffalo chicken, cheeses and scallions. Bake 18 minutes or until crisp.
