Directions

Wash and dry the cucumbers and tomatoes thoroughly. Slice the cucumbers, chop the tomatoes, and thinly slice the red onion. - Prepare the herbs.
Chop the parsley and optional fresh dill. Fresh herbs provide the brightest flavor, but dried herbs can be used if needed. - Make the dressing.

Place the cucumber, tomatoes, red onion, parsley, and dill in a large bowl. - Add the dressing.
Pour the dressing over the vegetables and gently toss until everything is lightly coated. - Rest the salad.
Allow the salad to sit for 10–15 minutes before serving. This gives the flavors time to blend while keeping the vegetables relatively crisp. - Taste and adjust.
Taste a small portion and adjust the vinegar, pepper, or salt as needed. Avoid adding excessive dressing. - Serve chilled or cool.
Serve immediately or refrigerate briefly before serving.
