Breakfast or dinner? That is the great thing about corn beef hash, it can sit as comfortably next to a side of eggs in the morning or a side of cabbage in the evening. It is great to have on hand when you need a hearty meal for the gang, but do not have a lot of time on your hands. If that sounds like you, then raise your hand. And not many people will turn up their noses at such a classic meal of meat and potatoes. You really can not go wrong. We dare you to mess it up.
