Honey Mustard Salad Dressing

Thick tangy golden dressing with only 4 ingredients; no mayonnaise. Serve over mixture of greens and fresh sliced mushrooms. From an old clipping from Taste of Home magazine. The salad I made was a mixture of spinach, romaine lettuce, thinly sliced red onion, fresh sliced mushrooms, small cubes of mozzarella cheese, and mandarin oranges drained, but you can use any combination of salad ingredients you like.
