Preheat oven to 375 degrees F. Heat large pot of water and bring to boil. Wash and prep fresh produce.
Heat dutch oven or large sauce pan over medium-high heat. Add ground beef and cook until nearly all beef has browned. Drain grease. Add onions, peppers, garlic, marinara, pizza sauce, Worcesteshire sauce, broth and Italian seasoning. Stir mixture, scraping the bottom, and bring to a simmer partially covered.
While pizza sauce mixture simmers, and once pasta water has started to boil, add pasta and cook according to the package. Drain the pasta and add to a 9 by 13 baking dish, followed by the sauce mixture. Stir to combine pasta and sauce mixture. Mix in half the mozzarella cheese and black olives. Top with remaining mozzarella and parmesan cheese and pepperoni.
