Begin by thoroughly washing your English cucumbers under cold running water. Using a sharp knife or a mandoline, slice them thinly, aiming for uniform thickness.

Next, take a small red onion and cut it into thin slivers. Gently sprinkle the onion slices over the cucumber layers in the deli container.

Dollop generous spoonfuls of softened cream cheese onto the cucumbers and onions in the container, spreading it evenly.

Add your preferred amount of mayonnaise into the container, fold the ingredients together without over-mixing.

Sprinkle your choice of toppings, such as toasted sesame seeds or seaweed, over the mixed salad and give everything a gentle toss.

Cover the deli container and place it in the refrigerator for at least 15 minutes before serving for optimal flavor.
