What do you do with leftover spaghetti? It's a pity to toss it, but it's never quite as good reheated. It's an eternal problem solved seamlessly by the recipe below: a delicious quiche filled with leftover spaghetti. Yes! Spaghetti quiche!
The best part about this recipe is that it doesn't matter what sort of sauce was on your original pasta: marinara, pesto, even alfredo will all go well with this quiche. If your original spaghetti was plain, you might want to add a bit more cheese to the quiche to make it even more flavorful.
