Peter,
Cutting the kingfish into cutlets and then either bbq or steam them in the microwave.
Another way is to gut the fish and fill its cavity with herbs (garlic,tomatoes,capers,olives,parsly, mint,salt and pepper).
Wrap the fish in foil sprinkle with lemon juice before sealing and then bake in the oven, make sure that the fish does not dry out.
Keep checking the fish parcel till it is cooked thru - the flesh should peel off the backbone.
Then serve with fresh salad or cooked veges.
