That's an excellent idea! For a little extra smokey flavor try
blackening it on your outdoor grill. Put a few chips of wood (hickory,
oak, fruit, or pecan) in a double layer of foil and punch a few holes
in the packet. Then put that on your coals or on the lower grate of a
gas grill. Close the lid and "you're smokin' " That will give you
about 15-20 minutes of sweet smelling smoke.
