Begin by thoroughly washing the English cucumber. Using a mandolin or a sharp knife, slice it into thin, even rounds, about 1/8 inch thick. Place the cucumber slices into a medium-sized bowl with a lid.

To the bowl of cucumber slices, add the sweet imitation crab meat, sliced green onions, a splash of soy sauce, and a generous dollop of spicy mayo. Sprinkle in kosher salt and black pepper. Stir gently with a spatula to mix and let it sit to absorb flavors.

Secure the lid on the bowl tightly, then shake vigorously for about 15-20 seconds to meld the ingredients together. Taste the mixture and adjust seasoning if needed.

Gently layer sliced avocado on top of the cucumber salad mixture. Drizzle with a bit of extra spicy mayo.

Sprinkle sesame seeds over the top and add a few pieces of pickled ginger or a dollop of wasabi if desired to enhance presentation and flavor.
