Preheat oven to 450F (230C) and roll out pizza dough into a 12” (30cm) circle. Transfer to a pizza pan and brush lightly with olive oil.

Transfer dough to center rack of preheated oven and bake for 9-10 minutes or until crust is just beginning to turn a light golden color. Do not turn off the oven.

Spread a spoonful of BBQ sauce evenly over the baked pizza. In a separate bowl, toss together the chicken and remaining BBQ sauce, then layer this evenly over the pizza crust.

Sprinkle the chicken with about half of the onion, red pepper and bacon, top evenly with shredded cheese, then sprinkle the remaining onion, bell pepper, and bacon evenly overtop.

Return pizza to center rack of oven and bake 10-13 minutes/until cheese is melted and bubbly. If desired, top with chopped scallions before serving. Allow to cool slightly before cutting and serving.
