Heres the recipe for my first attempt at grilling a whole fish. it was great
cedar plank same size as the fish or larger soaked in water for at least an hour
set the grill up for indirect heat if you have a thermometer heat the grill to 375-400 or so
1 whole snapper 3 lbs or so fins removed but head and tail on
4-5 sprigs fresh rosemary
1 tbsp lemon juice
cut 3-4 slits in the fish on one side
stuff cavity with rosemary sprigs
coat the plank with olive oil so fish doesnt stick
put the fish on the plank and sprinkle with the lemon juice
sprinkle the fish with the greek seasoning inside and out
place the plank on the grill and cook 30-40 minutes until the fish is no longer translucent.
remove to a platter,cut the head and tail off and remove the fillets from both sides to serve.
