  • For the Lime Crema 1/2 cup sour cream (or full-fat Greek yogurt)

Method
 

  1. Make the slaw: In a bowl, toss cabbage, cilantro, and red onion with lime juice, avocado oil, salt, and pepper. Set aside to soften slightly while you prepare the fish.
  2. Mix the crema: In a small bowl, whisk sour cream, mayonnaise, lime juice, hot sauce (if using), garlic, and a pinch of salt. Adjust lime and salt to taste. Chill until serving.
  3. Season the fish: Pat fish dry. In a separate bowl, combine chili powder, smoked paprika, cumin, garlic powder, onion powder, salt, black pepper, and lime zest. Sprinkle over the fish and gently rub to coat.
  4. Cook the fish: Heat avocado oil in a large skillet over medium-high. Add fish in a single layer. Cook 2–3 minutes per side until opaque and flakes easily. Avoid overcooking. Work in batches if needed.
  5. Prep the lettuce: Separate and rinse the leaves. Pat dry well so they don’t slip or water down the fillings.
  6. Assemble: Add a small handful of slaw to each lettuce leaf. Top with a few pieces of fish, a drizzle of lime crema, avocado slices, and any extras like jalapeño or cilantro. Finish with a squeeze of lime.
  7. Serve immediately: Lettuce wraps are best enjoyed right away while crisp and fresh.
