Preheat Grill to Medium Heat (450 degrees) with Outset Pizza Stone in center.
Lightly coat a large pizza peel with corn meal and roll out premade pizza dough. Allow to cook on a pizza stone for 4-5 minutes. Remove from heat to add toppings.
After cooking the chicken thoroughly, mix with BBQ sauce and shred.
Evenly distribute a layer of mozzarella, chicken, peppers and onions.
Bring back to grill and slide pizza onto pizza stone gently. Cook for 5-7 mins with the cover closed. Open grill and rotate pizza 180 degrees. Cover again and cook for an additional 5-7 mins, or until crust is lightly browned.
Use pizza peel to remove the pizza from grill and garnish with scallion to preference. Enjoy!
