Light & Tangy Buttermilk Dressing

For an interesting diversion from oil-based vinaigrettes, try this utterly delicious light-weight dressing that delicately coats leaves with a fresh, herby tang. While optimal on little gems, romaine, or other hearty lettuces, it is not overly viscous and thus also in good company with field greens. Salad additions such as sliced tomatoes, avocado, sweet onion, grated carrot and cucumber really make this dressing shine.
