My Favorite Baked Ziti

Ingredients:
16-oz. package Ziti Pasta
1 lb. lean Ground Beef
1 Onion, chopped
2 27-oz.cans Spaghetti Sauce
6 oz. Provolone Cheese, sliced
6 oz. Mozzarella Cheese, sliced or shredded
1 1/2 cups Sour Cream
1/2 cup Parmesan Cheese, grated

Cook pasta as directed on the manufacturer's packaging.
Drain and reserve.

Meanwhile, sauté the ground beef and chopped onion
in a heavy skillet over medium heat. Add spaghetti
sauce and simmer about 15 minutes.

Place about half of the pasta in a lightly oiled 2-quart
baking dish. Top with a layer of provolone and
mozzarella cheeses. Spread on a layer of about half the
sour cream and then half the spaghetti sauce mixture.
Cover with the remaining pasta, cheese slices, sour
cream, and sauce. Finally, sprinkle on a layer of
Parmesan cheese.

Bake in a pre-heated 350-F degree oven for about 30
minutes, or until the cheese and sauce are bubbly.
