This simple salad recipe features a twist on the original — in addition to the classic tomatoes, cucumbers, and red onion, celery is tossed into the mix for extra crunch and its clean, crisp flavor.
In a salad bowl, combine the tomatoes, cucumber, red onion, celery, and olives. Add the oregano and season with salt and pepper, to taste. Add the feta and toss to combine. Let stand for 15 minutes before serving. Just before serving, drizzle with olive oil and season with salt and pepper, to taste.
