Common Mistakes to Avoid

- Skipping the marinating time: Not allowing enough time for the vegetables to marinate can result in bland flavors. Aim for at least 30 minutes, but longer is better!
- Over-seasoning: While seasoning is important, adding too much salt or vinegar can overpower the dish. Start with less and adjust according to your taste.
- Using unripe tomatoes: Unripe tomatoes can be hard and lacking flavor. Choose ripe, juicy tomatoes for the best results in your salad.
- Not slicing evenly: Inconsistent vegetable sizes can affect the marinating process. Slice cucumbers, onions, and tomatoes uniformly for even flavor distribution.
- Ignoring fresh herbs: Fresh herbs elevate the dish’s flavor profile. Don’t skip this step; use parsley or dill for an extra burst of freshness.
