Preheat oven to 400 degrees. Cube chicken and fry in a skillet with two tbsp of olive oil. Salt and pepper to taste.
Roll out pizza dough on floured surface into a rectangle shape. Spread on ranch. Add chicken, cheese, and precooked bacon.
Roll dough up like a pinwheel and fold the ends to make sure nothing comes out while baking. Place on a baking sheet that has been lightly sprayed with non stick cooking spray. Bake for 20 minutes or until done. Remove and let cool for about 10 minutes. Slice and serve.
