Baked Ziti with Sausage

I was starving for this -- I haven't had it since a friend made it for me in college!

Chose the recipe at random on allrecipes.com -- and it worked out great.


Baked Ziti with Sausage
(Altered from AllRecipes.com)

1 lb. dry ziti pasta
1 onion, chopped
1 lb. sausage, loose of casings
2 jars spaghetti sauce (or equivalent of homemade)
6 oz. provolone cheese, sliced
1 1/2 cups sour cream (can also use cottage cheese)
6 oz. mozzarella cheese, shredded
2 tablespoons parmesean cheese

Directions
- Bring a large pot of lightly salted water to a boil. Add ziti and cook until al dente; about 8 minutes; drain.
- In a large skillet (with sides) brown the sausage and onion over medium heat. Drain off fat, then return to skillet. Add spaghetti sauce, and simmer 5 minutes.
- Preheat the oven to 350 degrees and grease a 9x13 baking dish.
- Layer as follows: 1/2 the ziti, all of the provolone cheese, all of the sour cream, 1/2 the sauce and sausage mixture, remaining ziti, mozzarella cheese, and remaining sauce and sausage mixture.
-Top with grated parmesean cheese.
-Bake for 30 minutes or until cheeses are melted.
