Not sure about the "Best" way but so far I have just filleted them, coated them in olive oil and put them straight on the BBQ. Skin side down, turn them remove skin and serve with fresh garden salad, curly fries and tartare sauce. They are one of the best tasting fish I have eaten and all of the kids 9 (fussy eater), 12, 19 and 21 come back for seconds. Given we have had a few recently I will be looking for other ways to cook them but for now plain and simple is a favourite.
