For marinade: Combine all marinade ingredients and stir well. Place tenderloins in a 9� by 13� dish and coat thoroughly with marinade. Cover and chill for 3 hours.
Grill tenderloins, covered, over hot coals for 30 to 45 minutes, turning once.
Note: For a smoky flavor, place tenderloins on the side of the grill and smoke over hickory chips for 1 hour.
