This Baked Ziti recipe from allrecipes.com is unique in that it has sour cream to give it a little zing! Of course having provolone, mozzarella, and parmesan cheeses doesn't hurt either! Give it a try! It is a big recipe so you'll have some yummy leftovers. I made mine in 2 smallers dishes because it is just the 2 of us here. I tossed the 2nd dish in the freezer to use on a busy night during the holiday season!
