My recipe has mayonaise, which also has oil. (You could use a low fat mayo. though I don't.) I make a dressing with 3 Tablespoons of mayo, 1 T. milk , 1 or 2 T. Balsemic vinegar, crushed clove of garlic, 1 t. sugar. Mix well and stir into the salad leaves gently, chill about 15 minutes before serving.
