Ingredients :

1lb Chilean sea bass fillet - (to 1 1/2 lbs) bones removed,cut into serving pieces
3/4 cup orange juice
3 tbs tomato paste
2 tbs vegetable oil
2 tbs vinegar
1 tbs brown sugar or honey
2 x garlic cloves minced or pressed
1 tsp grated orange zest
1 tsp ginger ground
1/2 tsp dried hot red pepper flakes

Method :

* Rinse the Chilean sea bass with cold water and pat dry with paper towels. Set the fish in a shallow dish. Stir together the remaining ingredients in a small bowl until well combined, then pour over the fish, turning the fish so that it is evenly coated. Cover and marinate in the refrigerator for 1 to 3 hours.
* Preheat a charcoal grill or the broiler. Grill or broil the fish about 4 inches from the heat until well browned on one side, 3 to 5 minutes; brush with more marinade and cook on the other side until the fish is no longer opaque in the center, about 5 minutes longer.
