Very simple:
Thaw out the filets
Dip coat the filet in melted butter/margarine
Sprinkle Prudhomme's Redfish Magic seasoning on them
Then take mod/finely crushed pecans and coat one side, then flip over and coat the other side.
Take a cast iron skillet and put it on your grill OUTSIDE( cause it smokes like mad)
Get the grill HOT as in "beads water" hot
Throw a bit of butter down , wait a second or two for a flash melt
Place filets in skillet, 4 min. DON'T TOUCH or mess with them
Flip the fish and 3-4 min on the other side , depends on thickness.
Take off and enjoy.
The oil from the pecans comes out from the heat and prevents the fish from burning. Plus the pecans are wonderful to eat as well!
