"THE SECRET of any salad is the dressing, and in this dressing the ingredient that makes the difference is red wine vinegar. Mixed with olive oil and Italian seasonings, this dressing enhances any kind of greens with a special flavor."
In a jar or bottle with tight-fitting lid, combine all the dressing ingredients; shake well. Chill. Just before serving, combine greens, onion, cucumber and tomatoes in a large salad bowl. Pour desired amount of dressing over salad; toss to mix. Top with the green pepper rings.
