I love oysters pretty much any way they can be used. One unique way that I am very fond of is to heat a small cast iron skillet on the smoker/grill and using Mesquite chips or pellets.
We did something similar when oysters weren't too expensive fresh, in the shell. With an oven mitt and a shucking knife, we would open and spread oysters on the half shell on a smoky grill, mesquite or hickory. Cover the grill for a few minutes, then pull the oysters off and eat from the shell with hot sauce. Was pretty good!
