Pre-heat the oven to 375. Lightly mist a baking sheet with cooking spray and set aside.

In a large skillet, cook the sausage over medium heat, breaking it up with a spoon. Once browned, add the bell pepper and continue to heat until cooked.

Unroll the pizza dough. Spread the spinach across the surface, followed by the sausage & pepper mixture. Sprinkle the pepperoni pieces across the top, followed by the shredded cheese. Starting with the short side, roll the dough, with the toppings inside, until you reach the other end. Tuck the ends of the roll under and pinch the seam to seal.

Place the roll on the prepared baking sheet. Spray the top and sides with cooking spray and then sprinkle with the Parmesan cheese. Bake for 25-30 minutes until golden brown. Let cool for 5 minutes before cutting. Cut into 12 slices and serve with pizza sauce.
