This delicious casserole is a twist on traditional pizza. It's made with pasta instead of crust, and loaded with pepperoni, cheese, and tomato sauce. To make this dish, you'll need 1 pound of pasta, 1 jar of tomato sauce, 1 package of pepperoni, 2 cups of shredded mozzarella cheese, and 1/4 cup of grated Parmesan cheese. Cook the pasta according to the package instructions, and then mix it with the tomato sauce and half of the pepperoni. Pour the mixture into a baking dish, and top with the remaining pepperoni and cheeses. Bake at 375 degrees for 20-25 minutes, or until the cheese is melted and bubbly. Serve hot and enjoy!
