01 - Combine green and red cabbage, carrot, and cilantro in a large bowl. Whisk together mayonnaise, Greek yogurt, apple cider vinegar, sugar, salt, and pepper in a separate small bowl. Pour dressing over vegetables and toss to coat. Refrigerate until needed.
02 - Pat fish fillets dry and cut into taco-sized strips. Mix Cajun seasoning, smoked paprika, garlic powder, onion powder, salt, and pepper in a bowl. Rub spice blend onto fish, drizzle with olive oil and lime juice, coating evenly.
03 - Heat a non-stick skillet over medium-high heat. Add fish strips and cook for 2-3 minutes per side until cooked through and lightly charred. Remove from heat.
04 - Place a portion of slaw on each warmed tortilla. Top with pieces of Cajun-spiced fish. Garnish with extra cilantro and a squeeze of lime juice.
05 - Serve immediately with lime wedges on the side.
