In a small mixing bowl, combine the cream cheese, minced spring onion, chopped chives, lemon juice, lemon zest, and black pepper. Mix until smooth and creamy.

Wash and dry the cucumber. Slice it into thick rounds, approximately half an inch thick. Pat dry to avoid excess moisture.

Spread a generous amount of the creamy mixture over each cucumber slice, then top with a piece of smoked salmon. Press gently to adhere.

Sprinkle extra black pepper and chopped chives on top. Drizzle with lemon juice for added brightness.

Arrange the bites on a serving platter. Serve immediately or refrigerate for up to an hour before serving.
