In a small bowl, mix the softened cream cheese, chopped dill, lemon juice, salt, and pepper until well combined.

Using a sharp knife or a mandoline, thinly slice the cucumber. Pat the slices dry with a paper towel to remove excess moisture.

If desired, lightly butter one side of each slice of bread. Spread a generous layer of the herbed cream cheese onto the unbuttered side of four slices of bread. Arrange the cucumber slices evenly over the cream cheese. Top with the remaining slices of bread, buttered side out.

Using a sharp knife, carefully cut off the crusts for a more elegant presentation. Then, cut each sandwich into quarters or halves, depending on your preference. Serve immediately and enjoy!
