Heat a 12inch
cast iron skillet on med-high heat. While the pan is heating up, coat
each side of the mahi with the blacken seasoning. Next, put I tablespoon
of butter in the cast iron skillet. The pan should be hot enough where
the butter instantly melts and starts to smoke.
Place the mahi pieces in the skillet to be cooked. Cook the fish 2-3 minutes on each side until done. Arrange by starting with tortilla shell, next put around 2-3 oz of mahi. Finally, drizzle with chipotle mayo and top with lettuce, tomato, onion and cilantro.
