Wash and thoroughly dry all vegetables.
In a large bowl, combine the chopped romaine lettuce, diced cucumber, chopped tomatoes, and thinly sliced red onion.
Add the Kalamata olives and crumbled feta cheese to the vegetable mixture, gently tossing to distribute evenly.
In a small bowl, whisk together the olive oil, lemon juice, dried oregano, salt, and pepper. Add optional garlic and honey if using.
Taste the dressing and adjust seasonings if needed.
Just before serving, pour the dressing over the salad and toss lightly to coat all ingredients evenly.
Garnish with extra feta crumbles and a sprinkle of oregano.
Serve immediately on chilled plates for the best flavor and texture.
