I've used mine to make hash. Chop up some onion, garlic and bell pepper...different colors of bell peppers if you have them. Chop up the potatoes in large-ish pieces, and saute them in fairly hot oil. The crawfish seasoning will enhance the flavor of the entire dish. If you want to make this a main dish, add some chopped ham or bacon or something. And to make it extra tasty, use some butter instead of (or in addition to) the oil. Not the healthiest dish, but yyyyuuuuummmmmmmmmyyyy.
Or just keep the potatoes whole and steam them to heat them again and put them on the side of any meal.
