In a large mixing bowl, combine the halved cherry tomatoes, diced cucumber, diced red bell pepper, halved kalamata olives, crumbled feta cheese, thinly sliced red onion, and chopped fresh parsley. Gently toss the ingredients together to mix them evenly.

Make sure to use fresh ingredients for the best flavor and texture. The combination of colors will also make the salad visually appealing.

In a small bowl, whisk together the extra virgin olive oil, red wine vinegar (or lemon juice), dried oregano, minced garlic, salt, and black pepper until well combined. This emulsifies the dressing, ensuring it coats the salad evenly.

Taste the dressing and adjust the seasoning if necessary. You can add more salt or vinegar based on your preference.

Drizzle the dressing over the salad and toss gently to coat all the ingredients evenly. This step is crucial as it enhances the flavors of the salad.

Serve immediately or let it chill in the refrigerator for about 15 minutes to allow the flavors to meld together. This salad is best served fresh but can be stored in an airtight container in the fridge for up to 2 days.
