Preheat the oven to 425°F (220°C).

Prep the ingredients per the instructions above.

Prepare the dough according to the directions on the package or if using homemade dough refer to the recipe directions.

Make BBQ chicken: Combine all ingredients in a saucepan (except the chicken) over medium heat and bring to a low simmer for 3 to 5 minutes. Then set aside. Preheat a grill or grill pan on medium heat. Brush some of the BBQ sauce on one side of the chicken. Place the chicken on the grill sauce side down, then brush the top side of the chicken with sauce. Cook on both sides, lightly brushing with sauce, to an internal temperature of 160℉ (71℃). Set aside to rest for 5 minutes then dice.

Clean and dry the counter well (make sure your hands are dried well before working with the dough). Sprinkle the counter with flour; place the dough on top of the flour, coating each side so the dough doesn't stick.

Begin stretching out the dough using your hands or a rolling pin. Make sure it is being stretched evenly and avoid creating thin spots in the center (if the dough starts to stick while stretching it, sprinkle flour to prevent it from sticking).

Gently place the dough on a baking sheet, pizza pan, or pizza stone. (Use nonstick spray when you are using the baking sheet/pan or semolina flour if using the pizza stone to prevent sticking.)

Evenly spread a layer of BBQ sauce on the dough, leaving about an inch of dough without sauce around the edge.

Evenly distribute the cheese over the sauce and top with chicken.

Bake the pizza in the oven for 10 minutes, then rotate the pan and bake until the crust is golden brown and crispy and the cheese is melted (approximately 10 minutes or more if needed).

Let the pizza sit for 2 to 3 minutes before cutting. Garnish with tomatoes and scallions.
