01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper and set aside.
02 - Pat the cod fillets dry with paper towels and arrange on the prepared baking sheet. Drizzle with olive oil, then sprinkle evenly with smoked paprika, ground cumin, garlic powder, salt, and pepper. Squeeze lime juice over the fillets and gently rub the seasonings to coat all surfaces.
03 - Bake for 12 to 15 minutes, or until the cod flakes easily when tested with a fork and reaches an internal temperature of 145°F.
04 - While the cod bakes, whisk together the sour cream or Greek yogurt, mayonnaise, minced garlic, lime juice, lime zest, and chopped cilantro in a small bowl until smooth. Season with salt and pepper to taste, then refrigerate until ready to serve.
05 - In a medium bowl, combine the shredded cabbage and julienned carrot. Drizzle with lime juice and olive oil, toss to coat evenly, and season with salt and pepper. Set aside.
06 - Heat tortillas in a dry skillet over medium heat for about 30 seconds per side, or wrap in a damp paper towel and microwave for 20 to 30 seconds until pliable.
07 - Remove the baked cod from the oven and gently flake into large, bite-sized chunks using a fork.
08 - Layer flaked cod pieces onto each warm tortilla. Top generously with the prepared slaw and drizzle with the creamy cilantro lime sauce. Garnish with fresh cilantro leaves and serve immediately with lime wedges on the side.
