Supreme Pizza-Style Pasta Recipe

Fold two 18-in.-long pieces of foil into two 18x4-in. strips. Line perimeter of a 5-qt. slow cooker with foil strips; spray with cooking spray. In a 6-qt. stockpot, cook sausage over medium heat until no longer pink, breaking into crumbles. Add pasta; cook and stir 3-4 minutes or until edges become translucent. Stir in pasta sauce, water, pepperoni, and half of each of the following: mozzarella cheese, pepper, onion, olives and mushrooms. Transfer pasta mixture to slow cooker. Top with remaining mozzarella cheese; sprinkle with remaining vegetables. Cook, covered, on low 3-4 hours or until pasta is tender. Just before serving, sprinkle with Parmesan cheese. If desired, serve with additional pasta sauce.
