Paige's Pasta Casserole

Boil one box of rigatoni or ziti in a large pot. Simultaneously brown
1 lb of ground beef. Drain, and add 2 jars of pasta sauce. Simmer on
low for about 5 minutes. Drain pasta.

Lightly grease a 9x13 pan. Layer 1/2 of dry pasta, 6 slices of
provolone cheese, 1 8-oz container of sour cream and 1/2 the meatsauce
mixture.

Then add the rest of the pasta, 1 bag of mozzarella cheese (fat free
works fine if you cover it with sauce-otherwise it doesn't melt), and
the rest of the meatsauce. Sprinkle Parmesan cheese lightly over top.

Bake at 350 for 45 minutes, cool for 5. I like to divide and freeze
the leftovers.
