Preheat oven to 350 degrees F and grease a 9x13 inch baking dish with cooking spray. Set aside.

Heat a large sauté pan over medium heat.

Once hot, add in Italian sausage, bell pepper, onion, mushrooms, Italian seasoning, garlic powder, dried oregano, dried basil, salt, and pepper.

Cook, breaking up the meat as you go, until the sausage is no longer pink.

Drain any grease, if necessary, then transfer to a very large mixing bowl.

Add in pepperoni, pizza sauce, cooked pasta, and 1/2 the mozzarella cheese.

Stir to combine, then taste and re-season, if necessary.

Pour into the prepared baking dish, then sprinkle with remaining mozzarella cheese and parmesan.

Cover the baking dish with tin foil that’s been sprayed with cooking spray (this prevents the cheese from sticking) and bake in the preheated oven for 25 minutes or until the cheese has melted and the center is hot.

Remove from the oven, then serve and enjoy!
