In a medium bowl, mix the whipped cream cheese with ranch seasoning until well blended.
Spread a generous layer of the cream cheese mixture onto one side of each slice of bread.
Place thin cucumber slices on half of the bread slices. Sprinkle lightly with salt and dill if using.
Top with the remaining slices of bread to make sandwiches.
Cut each sandwich into quarters (diagonals or squares—dealer’s choice).
Serve immediately or cover and chill until ready to serve.
