Ahh.. Tony Chacheres Original Creole Seasoning... I just used that tonight on my potatoes.

Love it!
I take like 4 or 5 potatoes, wash them off, and cut them into 1/4 inch slices. Then take an onion and cut it all up in slices. Melt a stick of butter. Use a 9 by 12 inch pan. First make a layer of onions, then potatoes and then pour some butter over it. Sprinkle Tony's seasoning over that layer. Then do another layer just the same until your potatoes are gone. Cover the pan with foil. Bake in the oven 400 degrees for about 50 minutes or potatoes are tender.
