Heat 1 tablespoon of vegetable oil in a cast iron skillet over medium high heat. Cook the fish for 3 minutes on each side, or until desired doneness. Let rest for a few minutes, then break up using a fork.
If desired, heat tortillas over an open flame until charred.
In each tortilla, layer 4 Alexia fries and some of the fish, then top with shredded cabbage and the Chipotle-Lime Dressing.
