Here's everything you need to get that smoky flavor on a gas grill, a non-stick, steel smoking box and a starter supply of wood chips. The "V"-shaped box nestles between the flame deflecter bars found on most gas grills, placing the smoking wood chips right below the food grate for maximum flavoring. The box has a hinged lid and a non-stick coating for easy clean up. Choose hickory or mesquite wood chips.
