Bring a large pot of salted water to boil. Cook pasta until al dente and drain. Set aside.
While pasta is cooking, break apart Italian Sausage in a large skillet over medium heat. Add in onion and garlic. Stir. Once Sausage is completely browned, add in bell peppers. Cook another 2 minutes to soften slightly.
Pour in marinara sauce, water and spices. Add in broccoli, if desired. Stir and simmer covered for about 10 minutes, OR until broccoli is cooked to your liking.
Toss with cooked pasta and top with parmesan cheese. Serve immediately.
