Wash the cucumbers thoroughly under cold water, then slice them into thin rounds, about ¼ inch thick.

Thinly slice the red onion and add it to the bowl with the cucumber slices. Toss gently.

In a separate bowl, whisk together sour cream, dill, vinegar, sugar, and salt until smooth.

Pour the dressing over the cucumber and onion mixture, and gently fold until evenly coated.

Cover and refrigerate the salad for about 10 minutes before serving.

Enjoy your salad with any additional veggies or proteins as desired.
