In a mixing bowl, combine the cream cheese, minced spring onion, chopped chives, lemon juice, lemon zest, and freshly cracked black pepper. Blend until smooth and creamy, about 2-3 minutes.

Select firm English cucumbers and wash thoroughly. Slice them into 1/2 inch thick rounds. Pat each slice dry with a paper towel.

Spread the creamy herb mixture over each cucumber slice, then place a piece of thinly sliced smoked salmon on top.

Garnish with additional chopped chives and black pepper. Chill briefly in the refrigerator before serving.
