Creating this salad is a breeze with these simple steps:

1. Prepare the Vegetables: Begin by washing the cucumbers, tomatoes, and parsley thoroughly. Slice the cucumbers into thin rounds, halve the cherry tomatoes, and chop the parsley. Thinly slice the red onion and set aside.
2. Make the Dressing: In a small bowl, combine the fresh lemon juice and olive oil. Season with salt and black pepper to taste. Whisk the ingredients together until well combined.
3. Assemble the Salad: In a large salad bowl, combine the sliced cucumbers, halved cherry tomatoes, sliced red onion, and chopped parsley.
4. Dress the Salad: Pour the lemon and olive oil dressing over the salad ingredients. Toss gently to ensure that the vegetables are evenly coated with the dressing.
5. Add Feta Cheese: If desired, sprinkle crumbled feta cheese over the top of the salad for an added layer of flavor.
6. Chill and Serve: Allow the salad to chill in the refrigerator for at least 30 minutes before serving. This will let the flavors meld together beautifully.
