Brush a large bowl with extra virgin olive oil. Roll the pizza dough into a ball, place in the bowl and turn to coat with the oil. Cover with plastic wrap and set aside in a warm place for about 30 minutes.
Position racks in the upper third and middle of the oven. Place a pizza stone or inverted baking sheet on the top rack and preheat the oven to 425° F, for at least 20 minutes.
Lay out a sheet of parchment paper and brush with olive oil. Transfer the ball of dough to the parchment and roll it out into a 10” round, stretching it as needed.
Place the Chick’n into a bowl. Mix with 2 tablespoons of Buffalo sauce and lightly season with salt and pepper.
Spread the remaining 1/3 cup of Buffalo sauce over the dough. Top with the Chick’n, cheese, red onion and bell pepper.
Slide the pizza (on the parchment) onto a pizza peel or another baking sheet and transfer to the hot stone or hot baking sheet. Bake until the cheese melts and the crust is golden, about 12 - 15 minutes.
Once you are ready to serve, top with fresh cilantro and drizzle with ranch dressing. Enjoy!
