Prep the vegetables: Slice the tomatoes into wedges, the cucumber into half-moons, and the red onion into thin slivers.
Add everything to a large bowl.
Add the olives and feta: Scatter the olives and feta over the vegetables. Keep the feta in larger crumbles for texture.
Make the dressing: In a small bowl, whisk together olive oil, lemon juice, red wine vinegar, garlic, dried oregano, a pinch of salt, and black pepper.
Toss gently: Pour the dressing over the salad and toss lightly with a large spoon and spatula. Avoid overmixing so the tomato wedges stay intact and the feta doesn’t turn to paste.
Add fresh herbs: Stir in chopped parsley, mint, or basil. Taste and adjust with more salt, pepper, or lemon if needed.
Rest briefly: Let the salad sit for 5–10 minutes so the tomatoes release some juice and the flavors mingle.
Serve: Transfer to a shallow platter and finish with a drizzle of olive oil and a pinch more oregano, if you like.
Serve with crusty bread to soak up the juices.
