Indirect grill method: Set up the grill for indirect grilling and preheat to medium-high. When ready to cook, place the macaroni and cheese in the center of the hot grate, away from the heat, and cover the grill. Toss the wood chips on the coals. Cook the macaroni and cheese until the sauce is bubbly and the top is crusty and brown, 40 minutes to 1 hour.
