Cast Iron Grilled Fish

steps

1. Heat grill to medium high (about 425 degrees). Have coals centered and close to the grate. Place a 10-inch cast iron pan directly over the coals to heat, about 4−5 minutes.
2. Season the fish with salt and pepper. Add fat into the pan and place fish in the pan. Close the lid and let them cook on one side until somewhat firm to the touch, about 5−8 minutes depending on thickness. Flip the fillets and immediately remove from the heat. Let fish rest a few minutes in the pan and serve.
