Summery Tomato and Cucumber Salad

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.
