Drain tuna; discard marinade. Spray cold grid of grill with nonstick cooking spray. Prepare coals for direct grilling. Place tuna on grid, 4 inches from hot coals. Grill 8 to 10 minutes or until tuna flakes easily when tested with fork, turning once during grilling. Slice tuna into 1/4-inch-thick slices; set aside.
