I bought the fish at Whole Foods and had it cleaned and butterflied.
Make a paste of cilantro, jalapeño peppers and onion with olive oil, ground turmeric and salt.
Generously rub the paste on the fish, both inside and outside. Stuff the fish with thyme sprigs, lemon slices and tomato half as shown in the picture.
Grill for about 10 minutes. Watch the heat, you don't want to burn the fish. Enjoy with your favorite white wine.
