In a medium bowl, combine softened cream cheese and ranch dressing mix packet. Stir until well-blended.
Slice cucumbers into relatively thin slices (I cut mine to approximately 1/4").
Slice baguette into medium slices (mine were about 1/2"). For a "daintier" sandwich, trim off crusts.
Spread cream cheese mixture onto one slice of bread. (I prefer a generous layer of the cream cheese mixture!).
Place 4-5 cucumber slices on top of cream cheese.
Spread cream cheese mixture onto a second piece of bread and place the bread on top of the cucumbers, cream cheese side down.
NOTE: I recently made this recipe for a bridal shower bruch I hosted. I knew the morning of the shower would be crazy, so I sliced the cucumbers and mixed up the cream cheese spread the night before. It tasted great and made things so much easier on the morning of the shower!
