The most simple dish to make in the world so long as you have a sauce to use.
16oz of Ziti or Rotini
4-6 cups shredded mozzarella or pre-packaged shredded 5 cheese blend
1/4 cup shredded Parmesan
Cook Ziti according ot directions on package. In 9x13 oven safe bake dish layer Sauce, Ziti, Mozzarella/cheese blend, Parmesan. Repeat.
Not at all gourmet but easy and fast and the kids will love it. I usually serve this with green beans for a more well-rounded meal!
