1. In a large bowl, combine the sliced cucumbers, sweet onion, and sea salt. Cover with plastic wrap and let sit for 15 to 30 minutes.
2. Turn the cucumber mixture into a colander set over a bowl or in the sink. Let drain, stirring occasionally, until most of the liquid and salt has drained, 15 to 30 minutes. Transfer drained cucumber mixture to a large bowl.
3. In a separate bowl, whisk together the mayonnaise, vinegar, sugar, dill weed, garlic powder, and ground black pepper until smooth.
4. Pour the dressing over the cucumber mixture and stir until evenly coated.
5. Cover the salad with plastic wrap and refrigerate for 1 to 2 hours before serving.
6. Enjoy this creamy, tangy salad as a refreshing side dish!
Notes
For extra crunch, you can add sliced radishes or bell peppers. Adjust the amount of mayonnaise and vinegar to reach your desired creaminess and tang.
