- Combine avocado flesh, buttermilk, mayonnaise, garlic, chives, and lime juice in a blender. Blend until smooth. Season dressing with salt and pepper.
- Combine shrimp and frisée in large bowl. Add enough dressing to thoroughly coat.
- Fill each bun with shrimp mixture, cabbage, and cilantro. Sprinkle with lime zest and serve.
*Notes: I recommend cooking the shrimp yourself over purchasing pre-cooked shrimp. A simple sauté in a little oil with salt and pepper will do just fine.
