Step 1

Add the cream cheese, sour cream, mayonnaise, lemon juice, garlic, chives, salt, onion powder, dill, and pepper to a medium-sized mixing bowl.

Step 2

Using a handheld mixer, mix on medium speed until smooth and well combined. This can be made and kept refrigerated up to 2 days in advance.

Step 3

To assemble the sandwiches, begin by very lightly buttering each slice of bread all the way to the edges. Then, spread a scant tablespoon of the dill sauce across each slice of bread. Reserve/use any leftover spread as a vegetable dip, if desired.

Step 4

Divide the sliced cucumber over half of the bread slices, slightly overlapping them. Top with the remaining bread slices and cut into triangles or rectangles. Serve and enjoy!
