When I have leftover spaghetti, I put it in a 9 x 13 baker, put a jar of spaghetti sauce, pepperoni (you could put your favorite pizza toppings), and if I have leftover bacon or sausage from breakfast I will put that in too, and cheese. Bake in oven at 350 degrees for 20 - 30 minutes and I have Spagetti Pizza.
