In a large salad bowl place the tomatoes, cucumber slices, olives, red onion, basil, mint and oregano.

In a small non-reactive bowl whisk together the red wine vinegar, lemon zest, salt, sugar, and pepper until the salt and sugar have dissolved. Add the oil in a thin, steady stream, whisking until completely incorporated. Pour dressing over salad and toss to thoroughly combine.

Let salad sit for 5 to 10 minutes for flavors to mingle, then serve.

Note: Salad ingredients may be prepared up to several hours in advance and refrigerated, undressed and covered with plastic wrap, until ready to serve. Add dressing and toss to combine just before serving.
