Melt 3 Tablespoons of Butter and add 2 Tablespoons of olive oil to create the buttery basting sauce. Then add a small hand full of chopped basil, a pinch of salt, and a pinch of pepper. Stir together and you have a great basting sauce for about any fish. If you do not have basil, I also love using fresh thyme to season fish.
Season both sides of the fish gently with the Plowboys Yard Bird seasoning, then coat both sides of the fish lightly with olive oil. Let it marinate for 20 minutes before grilling. An alternative to BBQ rub is using freshly cracked pepper and course sea salt. Season both sides before coating with olive oil.
Place the fish flesh side down over direct heat on the grill. I like to place the fish at a 45 degree angle to the grill grates, because I think it is easier to slide a spatula under. Cook for 2 minutes.
