Herbs de Provence is the belle of the ball in the salad dressing.  This mix of dried herbs is used heavily in French cuisine and contains thyme, basil, rosemary, tarragon, savory, marjoram, oregano, and bay leaf.  If you have all of those ingredients, by all means, make your own mix.  But in general, it’s much easier to buy a small packet of pre-blended herbs. To keep the salad from being too bland, the vinaigrette also has lime juice, Dijon mustard, and balsamic vinegar to perk up the beans.  The veggies add a nice crunch and pack in even more nutrients.
