My Personal Experience
- I always use the ripest tomatoes available.
Their natural sweetness creates the best flavor with very little seasoning. - Thinly slicing the onions makes a huge difference.
They become milder and blend beautifully with the tomatoes instead of overpowering them. - Letting the salad rest for a few minutes enhances the taste.
The dressing lightly marinates the vegetables, making every bite more flavorful. - Fresh basil is my favorite finishing touch.
It adds wonderful aroma and gives the salad a classic Mediterranean feel.
