Prep: Preheat oven to 425℉. Combine all ingredients for the Cajun seasoning.
Bake fish: Pat dry the fish with paper towels. Coat the fish well with the Cajun seasoning and bake for 15 minutes until cooked through and the fish flakes easily.
Combine slaw: In a large bowl, toss shredded cabbage with mayonnaise, sriracha, and lime juice.
Prep toppings: Prep all the toppings, such as diced tomatoes, sliced avocado, cilantro, and green onions. Set aside.
Flake fish: When fish has cooked through, remove from oven and flake with two forks. Transfer to a serving dish.
Assemble tacos: Heat tortillas on medium heat on an open flame or in a cast iron skillet. Add coleslaw to the bottom of the tortilla, followed by flaked fish, cilantro, green onions, avocado, and tomatoes. Drizzle with sriracha if desired, and serve.
