In shallow dish, combine lime rind and juice, oil, mustard and pepper;
add fish, turning to coat. Cover and marinate at room temperature
for 30 minutes, turning occasionally. Reserving marinade, remove fish;
sprinkle with sesame seed. Place on greased grill directly over medium
heat. Add soaked wood chips. Cover and cook, turning and basting with
marinade halfway through, for 16-20 minutes or until fish flakes easily
when tested with fork. Source: Canadian Living magazine [Jul 95] Presented
