This salad is so easy to throw together and can be made a few hours ahead of time. When my German aunt serves it, she usually does two or three other traditional salads and puts together a little salad plate for each guest as a starter to the meal.
- Combine the cucumbers, onions, tomatoes and parsley in a bowl.
- Mix up dressing ingredients separately, pour over the cucumber mixture and toss gently.
- Cover and chill for at least 1 hour.
