This refreshing cucumber tomato salad made with sliced cucumber, juicy tomatoes, and onion tossed in a sweet and tangy vinaigrette is easy to prepare, has tons of flavor, and is perfect for a warm summer day.
For optimal flavor, ensure the salad marinates for at least 2 hours, or even overnight, allowing the vegetables to fully absorb the vinaigrette. Consider a mandoline for uniform cucumber and onion slices, which ensures consistent texture and faster marination. Adjust the sugar and vinegar ratio to your preference, aiming for a balance of sweet and tangy. Adding fresh dill or parsley can elevate the aromatics. If tomatoes are very watery, gently scoop out excess seeds before cutting to prevent diluting the dressing.
