  3. Mix Together Then Refrigerate: Transfer dressing to bowl of cucumber and onion and, using a large spoon, toss to coat cucumbers and onions in dressing. Transfer to refrigerator to chill for at least 15 minutes.

Recipe Notes:

If You Have Extra Time Before Serving: You can give the cucumbers and onions time to release their liquid. Add the sliced cucumbers and onions to a colander and then sprinkle on 1 Tablespoon of salt. Toss the cucumbers around in the colander until the salt is evenly coating the cucumbers. Place the colander on top of a plate and then let them sit at room temperature for 1 hour (or up to 2 hours is fine, too!). After this time, transfer them to a clean plate lined with some paper towel and then, using another piece of paper towel, gently pat them dry to remove any excess moisture. If you plan to eat the salad right after preparing and chilling, you can skip this.

Refrigerator Storage: Store the salad in an airtight container in the refrigerator for up to 3 days.
