Ingredients

1 pound dry ziti pasta
1 onion, chopped
1 pound ground sirloin
2 (26 oz) jars of spaghetti sauce
8 slices of provolone cheese (real recipe calls for 6 oz, I like it cheesey)
1 1/2 cups of sour cream
8-9 oz shredded mozzarella cheese (real recipe calls for 6 oz again)
2 T grated parmesan cheese






Directions

1. Bring a large pot of lightly salted water to a boil. Add ziti pasta, and cook until al dente, about 8 minutes; drain.
2. In a large skillet, brown onion and ground beef over medium heat. Add spaghetti sauce, and simmer 15 minutes.
3. Preheat the oven to 350 degrees F (175 degrees C). Butter a 9x13 inch baking dish. Layer as follows: 1/2 of the ziti, Provolone cheese, sour cream, 1/2 sauce mixture, remaining ziti, mozzarella cheese and remaining sauce mixture. Top with grated Parmesan cheese.
4. Bake for 30 minutes in the preheated oven, or until cheeses are melted.
