Gut, descale, clean, and season the fish, then cut a bunch of spicy peppers, sliced tomato, bell pepper, onion, garlic, cilantro. Sear the fish then use the same pan to saute vegetables. Add tomato paste and water or broth to create the sauce, then place the fish back in. Usually you eat it with a fork but I prefer my fingers because it's easier to pick out the bones and meat in hard to reach areas like the cheek. If you marinade the fish for a few days it tastes even better. Usually this is eaten with rice
