How to Make It
Light a charcoal grill or heat 1 burner on a gas grill to moderately high. Season the trout inside and out with salt and pepper. When the coals are hot, rake them to one side. Sprinkle half of the wood chips over the coals. Or, for a gas grill, add the chips to a heavy-duty foil pan and set it directly on the burner. Oil the grill opposite the heat source.
Set the trout, backbone toward the heat, on the oiled grill. Cover and grill the trout for 15 minutes. Carefully turn the trout and sprinkle the remaining wood chips over the coals or add them to the foil pan. Cover and cook until the trout are opaque throughout, about 15 minutes more. Serve with the lemon halves.
