Sometimes simple is better. just saute them in butter with some crushed garlic(not to much) or garlic powder. Add some chopped green onions on top. A pinch of sea salt or salt and some pepper. Not much better than that. But creole would certainly be good to! Do it the same just add it instead of the salt.(Creole seasoning already has salt so don't add to much
Only if you like creole seasoning. I think it would taste great. As a matter of fact I would season the potato with the same seasoning. Add some of the seasoning to some sour cream to top the potato.
