Cucumber tomato onion salad is a crisp, cold side dish made with fresh cucumbers, tomatoes, red onion, and a simple vinegar dressing. It takes only a few minutes to prep, then the refrigerator does the rest. Serve it with grilled chicken, burgers, ribs, pork chops, or any meal that needs something fresh on the side.
In a large bowl, add the cucumbers, tomatoes and onions.
In a small bowl or salad dressing shaker, thoroughly combine the oil, vinegar, sugar, salt and pepper. Pour the dressing over the cucumber mixture and stir.
Refrigerate for 30 minutes. Serve garnished with dill, if desired.
