Begin by slicing the English cucumbers into 1/8-inch rounds. After slicing, sprinkle them lightly with salt and let them drain in a colander for about 15-20 minutes.

In a large mixing bowl, combine the drained cucumber rounds with diced crab (or imitation crab) and cubed avocado. Gently stir the mixture to combine without mashing the avocado.

In a separate bowl, whisk together the mayonnaise, cream cheese, soy sauce, and sesame seeds until smooth. Adjust the quantities to taste.

Pour the prepared dressing over the cucumber mixture, then gently toss all the ingredients together until nicely coated.

You can serve the salad immediately or let it chill in the refrigerator for about 10 minutes before serving.
