Place the halibut fillets in a shallow nonreactive baking dish. In a small bowl, whisk together the remaining ingredients. Pour marinade over fish, cover dish with plastic and let marinate in the refrigerator for 2 to 4 hours.
Heat a grill. Sprinkle the fish with salt and pepper and grill about 3 to 4 minutes on each side, or until cooked through. Serve hot with lime wedges.
