For vegetables :
5 large tomatoes (fresh and ripe; vine-ripened tomatoes are a very good choice)
1 pinch of brown sugar
1 English cucumber (fresh and firm)
1/2 large red onion
2 tablespoons fresh Italian parsley, chopped
2 tablespoons chopped fresh coriander
1 pinch of kosher salt
1 pinch of black pepper
For the dressing :
1/2 cup of extra virgin olive oil (very good quality)
1/4 cup red wine vinegar
freshly ground black pepper (to taste)
1 teaspoon of kosher salt
2 cloves of garlic (pressed)
1 teaspoon brown sugar
1 teaspoon dried oregano
Seed the tomatoes, cut them into 6 to 8 quarters, then cut each quarter in half. Place the tomatoes in a large bowl, sprinkle them with a pinch of brown sugar, salt and pepper and mix well.
Cut the cucumber in half lengthwise, then cut it into slices 1/4″ thick. Add the cucumbers to the tomatoes.
Cut half of the red onion into very thin slices across the width. Then cut the slices in half or leave them as they are, as you prefer. Add to the cucumbers and tomatoes. Add the chopped parsley and coriander.
To make the dressing, toss all the ingredients in a small bowl and whisk vigorously until well blended.
Pour the dressing over the vegetables and stir gently with both hands. Cover the bowl with plastic and let stand at room temperature until ready to serve for 1 to 6 hours. This will allow the flavors to blend. Then serve and refrigerate leftovers for up to 3 days.
