Spaghetti can be pretty boring. Thanks to the way our grocery store experience works, what ends up on most dinner tables is sauce from a jar, ground beef or sausage, and a nasty powdered mess that purports to be Parmesan cheese. It's rarely bad. It's also not a food that elicits excitement. But it isn't that hard to make a good sauce at home, and you don't have to be an Italian grandma to do it.
