Combine the soy, lime juice and ginger together. Pour over the fish and leave to marinate for 30 minutes.
Thread 2 pieces of the fish on small soaked bamboo skewers and grill for 6 - 8 minutes on a pan heated with the sesame oil, turning once.
Tastes great with Coriander and Lime dipping sauce (see recipe database).
