1 (16 ounce) package ziti pasta
24 ounces ricotta cheese
1 pound shredded mozzarella cheese
1 egg, beaten
1 (32 ounce) jar spaghetti sauce
1/4 cup grated Parmesan cheese
Bring a large pot of lightly salted water to a boil. Add ziti and cook for 8 to 10 minutes or until al dente; drain and rinse.In a medium bowl, mix ziti, ricotta cheese, mozzarella cheese, egg and 1 1/2 cups spaghetti sauce.Preheat oven to 375 degrees F (190 degrees C).Lightly grease a 9x13 inch baking dish and spoon in ziti mixture.

**I sometimes add cooked ground beef or Italian sausage in the spaghetti sauce**
