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

Wash and pat dry the cucumbers. Slice them into approximately 1/2 inch thick rounds and arrange on a serving plate.

Spread a generous amount of the cream cheese mixture onto each cucumber slice, and top with a small piece of smoked salmon.

Sprinkle cracked black pepper over the bites and garnish with chopped chives. Drizzle lemon juice over the top before serving cold.
