Cut the ends from the cucumber and discard.

Peel the cucumber with a peeler until all of the dark green has been removed.

Cut the cucumber in half lengthwise.

Take one half into your hand. Place the tip of a spoon just where the seeds begin.

Run the spoon down the center of the cucumber to remove the seeds.

Cut the cucumber half into long, thin strips.

These strips should be equally spaced to achieve equal-sized dice.

Lay a few of the strips next to each other and run your knife across them to create cubes.

The size of your diced cubes can be adjusted by changing the width of the strips.
