This is how you make Sbarro (Italian fast-food restaurant) style ziti.
Ingredients: ricotta cheese, romano cheese, mozarella cheese, tomato sauce, pepper, ziti pasta. (You can also add other seasonings of your choice such as parsley, rosemary, salt, italian spice mix, etc.)
You cook ziti pasta according to the instructions. In a bowl, you combine ricotta cheese, romano cheese (go easy on the romano), tomato sauce, and peper. You'll get a light pink mixture.
Then you add your cooked past to the pink mixture from above and gently mix/fold it....being careful not to break the pasta. The pasta should be mixed well/coated with the pink mixture.
Take a baking dish and line it with aluminum foil. Spread some tomato sauce on the bottom (as this will prevent the pasta from sticking). Next, add and spread the ziti/ricotta mix evenly in the dish. Sprinkle some shredded mozarella cheese on the top. Preheat oven at 350 degrees farenheit and bake for 12-15 minutes or until mozarella cheese on the top has melted.
