2 boxes of ziti, cooked according to the directions
1 large jar of Prego (or I usually do 3 of the heart healthy smaller jars)
1 large onion, chopped
1 lb ground beef
1 lb ground pork sausage
16 ounces of sour cream
8 ounces of ricotta cheese
1 cup shredded mozarella cheese
8 slices of provolone cheese
1/2 cup Parmesan cheese
In a large skillet, saute the onion for 5 minutes. Add the ground pork sausage and ground beef and brown. When it is all cooked, pour the meats and the pasta sauces into the cooked ziti, and stir.
In a seperate bowl, stir together the sour cream, ricotta cheese, and mozarella. I usually add a sprinkle of dried parsley, dried basil, dried oregano, and fresh black pepper.
Grease 2 9x13 baking dishes. Spread a layer of the pasta with sauces (1/4 of the total in each dish so you'll use half of the pasta in this layer) in the bottom of each dish. Top with a spreading of the sour cream/ricotta/mozarella mixture, then 4 slices of provolone cheese per dish. Repeat the pasta and sauce layer then the sour cream/ricotta/mozarella layer, then top with a sprinkling of Parmesan cheese.
If you're going to freeze them, wrap them tight with plastic wrap and freeze them now.
To finish (a fully-thawed dish), bake at 350 for 30 minutes or until the sauce is bubbling and the cheeses are melted.
