01 - Pat fish fillets dry and cut into strips. Toss with olive oil, Cajun seasoning, salt, and black pepper until evenly coated.
02 - Heat a large nonstick skillet over medium-high heat. Cook seasoned fish 2–3 minutes per side until cooked through and lightly charred. Remove from heat and set aside.
03 - Combine green cabbage, red cabbage, carrot, and cilantro in a large bowl. Whisk mayonnaise, Greek yogurt, lime juice, honey, and salt in a small bowl. Pour dressing over slaw and toss until well coated.
04 - Warm 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.
