In a bowl, mix the cream cheese with lemon juice, fresh dill, salt, and black pepper until smooth.

Slice the cucumbers into thin strips (use a mandoline slicer for best results).

Spread a thin layer of cream cheese mixture onto each cucumber slice.

Place a slice of smoked salmon on top of the cream cheese.

Carefully roll up the cucumber slice into a tight roll and secure with a toothpick.

Arrange the rolls on a serving plate and serve chilled.
