Preheat your oven to 400 degrees F and lightly spray a 13 x 9 inch baking or casserole pan with cooking spray. Add 1/2 cup of pizza sauce to the bottom of the pan and spread with a spoon or spatula. Set aside.
Spoon in ground meat into each bell pepper. Top each with 2-3 tablespoons of pizza sauce and a small handful of cheese. Top with your favorite pizza toppings (I used olives and pepperoni). Add the remaining pizza sauce to the bottom of the pan and spread it out with a spoon if you can.
