Cook rigatoni according to package directions and drain.
In a 10 inch skillet cook the bacon over medium heat, stirring occasionally, until the bacon is browned. Add the broccoli and garlic. Cook, stirring occasionally, until the broccoli is slightly tender (about 4 to 5 minutes).
Stir in the cooked rigatoni, mozzarella cheese, parmesan cheese and cayenne pepper. Cook, stirring occasionally, until the cheese is melted. Sprinkle with the fresh chopped parsley.
