1 In a large salad bowl, combine beans and tomatoes. 2 In a small bowl, combine olive oil, vinegar, oregano, pepper, and salt-free seasoning blend. Using a wire whisk, beat the ingredients until they blend into one thick sauce at the point where the oil and vinegar no longer separate. 3 Pour the dressing over the beans and tomatoes, and mix gently to coat. 4 Line four salad bowls with one romaine lettuce leaf each. 5 Top each leaf with one-fourth of the bean mixture, and serve.
