Pre-heat oven to 375 degrees.
Lightly sprinkle salt and pepper on both sides of chicken breasts and place in an oven-safe baking dish. Pour ¾ cup BBQ sauce over the chicken making sure to coat both sides. Bake for about 15-20 minutes, until the chicken is cooked through and registers at 165 degrees.
Remove chicken from the oven and increase oven temperature to 500 degrees. Let chicken cool slightly and dice into small cubes.
Divide pizza dough into two portions and roll and stretch one out to fit on a rimmed sheet pan sprinkled lightly with corn meal. Drizzle with a touch of olive oil and season lightly with salt.
Drizzle 3 Tbsp BBQ sauce over dough and smooth out with a brush or the back of a spoon. Place half of the fresh mozzarella on dough, add half the chicken, sprinkle half the smoked gouda, and add half the sliced onion. Repeat with second portion of dough.
