Baked Ziti with Sausage from Maggiano's? - italian baked ziti

My roommate has this one day behind the restaurant, and it was amazing .... So I have a very simple recipe for tonight.

I:

Penne
Vodka Sauce
Onion
Garlic


I just thought likely to buy some mushrooms and Italian sausage, and that's all. Opinions?
