Our friend Jessica calls this "the ultimate college recipe." Translation: The easiest recipe in the world. I agree wholeheartedly. So easy and my little boy LOVES it!
1 lb. penne noodles, cooked and drained
Pepperoni (I used the minis, but Tori uses the big ones and cuts them up.)
A jar of your favorite store-bought pasta sauce (I use Classico brand.)
Shredded mozzarella cheese (As much as you'd like. I like a LOT.)
Boil noodles. Drain and return to pot. Dump jar of sauce and pepperonis into the pot and stir. Dump the mixture into a greased casserole dish. Top with shredded mozzarella cheese. Bake at about 325 until warm and the cheese is melted. (30 mins?) We put foil over the top for the first 20 minutes so the cheese wouldn't get too crusty.
