1 pkg jumbo pasta shells
1 jr. spaghetti sauce
1 bag frozen cooked Italian meatballs; thawed (found near the frozen "snacks"; pizza rolls, bagel bites, etc)
1 cup mozzarella cheese
1 cup parm cheese
Cook pasta according to package. Drain and rinse with cold water, so its not too hot to stuff! Place a little bit of sauce in a greased baking pan. Place a meatball in each shell, and transfer to baking dish; open end down. Top with remaining sauce and sprinkle with both cheeses. Cover and bake at 350 for 35 minutes. Uncover and bake 5-10 minutes more; until cheese is melted and bubbly.
