Begin by thoroughly cleaning out your fish, pat the outside AND inside dry with a paper towel. Make 3 diagonal cuts along the body, then make another 3 cuts to make a criss cross pattern. Repeat on the other side.
Sprinkle both sides with the sea salt, pepper, turmeric, and lemon juice. Rub it into the fish with your hands, set aside.
In a small bowl, mix together the garlic, ginger, basil, parsley, Korean chili flakes, and olive oil. Add the mixture to both sides of the Pompano, make sure to get it into the cut.
Oil a cast iron grill and grill both sides for about 3-4 minutes, adding oil as necessary to prevent sticking. Remove, plate, and enjoy warm!
