In a medium bowl, combine the softened cream cheese, olive oil, lemon juice, chopped herbs, grated garlic, salt, and pepper.
Use a fork or a small spatula to mix everything together until the spread is smooth and uniform.
Taste the mixture and adjust the seasoning with more salt or lemon juice if desired.
Lay the four slices of bread on a cutting board.
Divide the cream cheese spread evenly and apply a generous layer to one side of each bread slice.
Arrange the cucumber slices in a single layer on two of the bread slices, placing them on top of the cream cheese.
Place the remaining two bread slices on top, cream cheese side down, to complete the sandwiches.
Gently press down on the sandwiches. If you like, trim the crusts off.
Cut the sandwiches in half, either diagonally or straight across, and serve immediately.
