Ingredients
4 large ripe tomatoes, assorted colors preferred (heirloom or vine-ripened)
1 large red onion, thinly sliced
3 tablespoons extra virgin olive oil
2 tablespoons red wine vinegar or balsamic vinegar
1 teaspoon sea salt (adjust to taste)
½ teaspoon freshly ground black pepper
1 teaspoon sugar or honey (optional, to balance acidity)
2 tablespoons fresh parsley, chopped
1 teaspoon fresh oregano or ½ teaspoon dried oregano
Optional garnishes: crumbled feta cheese, sliced black olives, fresh basil leaves
Instructions
Step 1: Prepare the Ingredients
Wash the tomatoes thoroughly and remove any stems or blemishes. Slice the tomatoes into uniform wedges or bite-sized pieces, ensuring they are thick enough to maintain shape during marination.
Peel the red onion and slice it thinly into half-moons or rings. Uniform slices allow for even marination and ensure a balanced flavor in every bite.
Chop the fresh parsley and oregano finflavourf using dried oregano, measure it accurately.
Step 2: Assemble the Salad Base
In a large mixing bowl, combine the sliced tomatoes and red onions.
Sprinkle sea salt over the mixture. The salt not only seasons the vegetables but also draws out excess moisture, enhancing the salad’s flavour.
Step 3: Prepare the Dressing
In a small bowl, whisk together the olive oil, vinegar, and optional sugar or honey. Adjust vinegar according to taste preference—red wine vinegar for a sharper tang and balsamic for a sweeter touch.
Stir in freshly ground black pepper, ensuring even distribution.
Step 4: Marinate the Salad
Pour the dressing over the tomato and onion mixture.
Add chopped parsley and oregano to the bowl.
Gently toss the salad until all ingredients are evenly coated with the dressing.
Cover the bowl with plastic wrap or transfer to an airtight container and refrigerate for at least 30 minutes to 1 hour. Marination allows the tomatoes and onions to absorb the flavors and release natural juices, creating a harmonious balance.

Tips
Use the freshest tomatoes you can find—ripe, firm, and fragrant tomatoes yield the best flavour.
Thinly slice onions to ensure they marinate well and do not overpower the salad.
Adjust salt and acidity after marination to suit your taste preference.
Letting the salad marinate longer (2–3 hours) intensifies the flavours, making it more aromatic.
For added crunch, include toasted nuts or seeds like pine nuts or pumpkin seeds.
This salad pairs well with grilled meats, fish, or even as a topping on crostini.
