Make the dressing. Combine the vinegar, salt, and sugar in a small mixing bowl. Stir until the salt and sugar dissolve.
Prep the veggies. Cut the cucumber in half lengthwise, then use a spoon to scrape out the seeds. Cut into ¼ inch thin slices. Cut the onion into very thin slices.
Combine and chill. Put the veggies in a mixing bowl and pour the dressing on top. Stir to combine, then cover and chill for at least 2 hours.

The thinner you slice the cucumbers, the faster they will absorb the dressing, but thicker slices will stay crisp longer. It's up to you 😊!

Make sure all the sugar dissolves before you add the veggies.

If you have any leftover cucumber salad, store it in the fridge in an airtight container. Leftover salad will last for 3-4 days.
