Cook pasta but not completely, drain and transfer to a large bowl.
Brown Italian sausage in a skillet. Drain grease and to the bowl of pasta. Add the raw chopped green peppers, tomatoes, onions, mushrooms, barilla sauce and 200g/7oz of the mozzarella cheese. Toss until fully combined.
Spoon pasta into a butter greased baking dish and top with remaining mozzarella cheese, parmesan, pepperoni, sliced black olives and oregano.
Cover with baking foil and bake in oven 190C/375F for 30 minutes. Remove foil and continue to bake for an additional 30 minutes or until cheese is fully melted and slightly browned on top.
Enjoy! 😊
