01 - Pat the fish fillets dry and cut into strips. In a bowl, toss with olive oil, Cajun seasoning, salt, and black pepper until evenly coated.
02 - Heat a large nonstick skillet over medium-high heat. Add the seasoned fish and cook for 2–3 minutes per side until cooked through and lightly charred. Remove from heat and set aside.
03 - In a large bowl, combine green cabbage, red cabbage, carrot, and cilantro. In a small bowl, whisk together mayonnaise, Greek yogurt, lime juice, honey, and salt. Pour the dressing over the slaw and toss until well coated.
04 - Warm the corn tortillas in a dry skillet or directly over a gas flame until pliable.
05 - Place a generous spoonful of slaw on each tortilla, top with Cajun-spiced fish, and garnish with lime wedges, jalapeño slices, and extra cilantro if desired. Serve immediately.
