Prepare outdoor grill for high heat.
Trim the tail and fins off of the salmon. Make several shallow cuts across the salmon's skin. Place salmon on 3 large
slightly overlapping sheets of aluminum foil.
In a bowl
stir together soy sauce
chile sauce
ginger
and garlic. Mix in lime juice
lime zest
and brown sugar. Spoon sauce over the salmon.
Fold the foil over the salmon
and crimp the edges to seal.
If using hot coals
move them to one side of the grill. Place the fish on the side of the grill that does not have coals directly underneath it
and close the lid. If using a gas grill
place the fish on one side
and turn off the flames directly underneath it; close the lid. Cook for 25 to 30 minutes. Remove to a serving platter
and pour any juices that may have collected in the foil over the top of the fish. Sprinkle with green onions.
