Well I had trouble sourcing bannana leaves so wrapped the fish in foil.
In the gut cavity - lime segments, shallotts, coriander leaves and grated ginger. On the BBQ for 25 minutes (indirect heat under the hood).
On to a platter and pour over a sauce of fish sauce, ginger, chopped coriander, shallots and lime juice.
Served with stir fried buk choy.
Lovely.
