Prep the vegetables: Slice the cucumbers, chop the tomatoes, and thinly slice the red onion. Aim for uniform bites so each forkful tastes balanced.
Soak the onion (optional): If you want a milder onion flavor, soak the slices in cold water for 10 minutes, then drain and pat dry.
Make the dressing: In a small bowl, whisk together the olive oil, lemon juice, red wine vinegar, salt, and pepper.
Add oregano or sumac if using.
Combine: Add the cucumbers, tomatoes, and onion to a large bowl. Pour the dressing over the top and toss gently.
Add herbs: Fold in the chopped parsley (or your herb of choice). Taste and adjust seasoning with more salt, pepper, or lemon as needed.
Rest briefly: Let the salad sit for 5–10 minutes so the flavors meld and a light, natural juice forms.
This makes the salad extra refreshing.
Optional upgrades: Sprinkle in feta, avocado, or olives right before serving for extra richness or tang.
