Greek Salad (Horiatiki Salada)

I make this traditional Greek salad with vine-ripened tomatoes, cucumber, feta, Kalamata olives, and red onion. I drizzle everything with red wine vinegar, olive oil, and dried oregano. It is so easy to make that in just 15 minutes, I can have this delicious side dish ready to pair with steaks, grilled mains, or enjoy on its own.
