Gather all ingredients and ensure the fresh crab meat is cold. Cut the avocado in half, remove the pit, and scoop the flesh into a mixing bowl. Squeeze half a lemon over the avocado to prevent browning.

Combine fresh crab meat with mayonnaise, lemon juice, and a dollop of wasabi in the mixing bowl. Fold gently to maintain texture.

Add the avocado to the crab mixture, gently folding to combine. Add chopped herbs and mix carefully.

Season the salad with salt and pepper to taste, mixing gently to ensure even distribution.

Transfer the salad to serving dishes over fresh greens or in chilled bowls. Garnish with herbs or lemon. Serve immediately.
