When your toddler discovered butter noodles you can spruce them up by making this version of butter spaghetti. It's simple quick and adds a bit of nutrients to an otherwise simple meal.
Note 1: I like to use unsalted butter for two reasons. The first is that I try to minimize the amount of salt I feed my kids. And the second reason is that the parmesan will add salt to the dish which I believe to be enough.
