How to Make It
To prepare dressing, combine lime rind, juice, oil, sugar, fish sauce, salt, and ground red pepper, stirring with a whisk.
To prepare salad, place celery and next 4 ingredients (through crabmeat) in a medium bowl; toss gently to combine. Drizzle dressing over salad; toss gently to coat. Place 1 lettuce leaf on each of 4 plates; spoon 1 cup salad into each leaf.
