Salt the cucumbers. Add the sliced cucumber to a colander and toss with the salt. Set the colander in your sink or on top of a plate, as the salt will pull liquid from the cucumbers. Let this sit for 20 minutes.
Wash and drain. Rinse the cucumbers with cold water, making sure to remove most of the salt.
Add ingredients to a bowl. Add the drained cucumber to a mixing bowl along with the red onion, green onion, and fresh dill.
Make the creamy dressing. In a small mixing bowl, stir together the sour cream, vinegar, garlic, and black pepper.
Stir together. Pour the dressing on top of the salad and stir to combine.
