Wash the cucumber and slice it thinly, discarding the ends. Place the cucumber slices on paper towels to absorb excess moisture.

In a medium mixing bowl, combine the softened cream cheese, chopped dill, salt, and pepper. Mix until smooth and well combined.

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

Place a cucumber slice on top of each cream cheese-covered bread slice.

Top with another bread slice to form a mini sandwich.

Repeat until all the bread slices are used up.

Arrange the mini sandwiches on a platter, and garnish with fresh dill sprigs, if desired.

Serve immediately, or cover and refrigerate until ready to serve.
