In a medium bowl, combine softened cream cheese with minced spring onion, chopped chives, lemon juice, lemon zest, and freshly cracked black pepper. Mix until smooth and creamy.

Wash cucumbers under cold water, then slice into half-inch thick rounds. Pat each slice dry with a paper towel.

Arrange dried cucumber slices on a serving platter. Spread an even layer of cream cheese mixture over each cucumber slice.

Place a slice of smoked salmon on top of each cream cheese-covered cucumber. Fold or roll the salmon for presentation.

Sprinkle extra cracked black pepper and chopped chives over each bite. Drizzle with fresh lemon juice if desired. Serve immediately.
