01 - Whisk together mayonnaise, lime juice, honey, salt, and black pepper in a large bowl. Add green and red cabbage with julienned carrot. Toss until thoroughly coated. Refrigerate until serving.
02 - Combine sour cream, mayonnaise, lime juice, hot sauce if desired, and pinch of salt in a small bowl. Stir until smooth and set aside at room temperature.
03 - Pat fish fillets dry with paper towels. Generously coat both sides with Cajun seasoning, salt, and black pepper, pressing gently to adhere.
04 - Heat olive oil in a large nonstick skillet over medium heat. Place seasoned fish in pan and cook for 2–3 minutes per side until fish is opaque throughout and flakes easily with a fork. Transfer to a plate and break into large chunks.
05 - Heat tortillas in a dry skillet for 30 seconds per side or microwave wrapped in damp paper towels for 20–30 seconds until soft and pliable.
06 - Place portioned fish chunks onto each warmed tortilla. Top with chilled cabbage slaw, drizzle with creamy sauce, and garnish with fresh cilantro leaves. Serve immediately with lime wedges on the side.
