Baked Ziti

1 lb ziti noodles
1 onion, chopped
1 lb ground beef or turkey
2 26 oz jars pasta sauce
6 oz provolone
1 1/2 cups sour cream
6 oz mozzarella cheese (about 3/4 cup)
2 Tbsp Parmesan cheese

1. Brown beef; drain. Add onion and sauce to beef, simmer 15 min.
2. Cook ziti noodles 8 min; drain. Grease 9x13 pan.
3. Layer 1/2 ziti, all provolone, all sour cream, 1/2 sauce, 1/2 ziti, all mozzarella cheese, rest of sauce. Sprinkle with Parmesan on top.
4. Bake at 350 for 35-45 min.

You can substitute penne or any tubular noodle that is similar to ziti. Also buy the slices of provolone and just lay them over the noodles and it works great! You can slice or shred the mozzarella, but I like mine shredded best.

I got this recipe from a co-worker years ago.
