Test Kitchen Tips:
•Grape wood chips are available in hardware, houseware and online specialty stores.
•If you do not have a smoker tray, place drained wood chips in center of a 12-inch square piece of heavy duty aluminum foil. Bring up 2 opposite corners; fold down to close, making 2 or 3 tight folds. Fold to close remaining open sides, making 2 or 3 tight folds. Poke several large holes on top to allow smoke to escape. Place foil packet directly on grill rack over lit burner.
• Top with 4 slices of cooked bacon and avocado slices, if desired.
