This refreshing cucumber tomato onion salad comes together in under 15 minutes with simple ingredients. The sweet-tangy dressing perfectly balances crisp cucumbers, juicy tomatoes, and mellow red onions, making it an ideal side for summer gatherings.
For best flavor, let the salad rest for at least 10 minutes before serving. If making ahead, salt the cucumber slices and let them sit in a colander for 15 minutes to draw out excess moisture. The salad can be stored in an airtight container in the refrigerator for up to 3 days, but the cucumbers will soften over time.
