Common Mistakes to Avoid
- Using watery vegetables without draining them — Excess liquid can dilute the dressing.
- Slicing the onion too thickly — Thin slices distribute the onion flavor more evenly.
- Dressing too early — The vegetables can lose their crisp texture if left in dressing for too long.
- Over-salting — Tomatoes and cucumbers release water when salted, so season gradually.
Required Equipment
- Sharp knife — Makes clean, even vegetable slices.
- Cutting board — Provides a stable surface for quick chopping.
- Large mixing bowl — Gives enough room to toss the salad without crushing the vegetables.
- Small bowl — Makes mixing the dressing simple.
- Whisk or fork — Quickly combines the oil and vinegar.
Storage Instructions
Store leftovers in an airtight glass or food-safe container in the refrigerator for up to 2 days. For the best texture, keep the dressing separate and combine it with the vegetables shortly before serving.
This salad is not recommended for freezing because cucumber and tomatoes become soft and watery after thawing. If preparing ahead, chop the vegetables and store them separately from the dressing.

- 2 tbsp fresh parsley, chopped
Dressing
- 2 tbsp extra-virgin olive oil
- 1 tbsp apple cider vinegar or white vinegar

Directions
