With just a few pantry staples, you can whip up a healthier homemade ranch dressing. Light mayonnaise gives the dressing body with less fat and calories than traditional versions, while buttermilk adds that signature tanginess. We like the convenience of using dried dill, but if you have fresh on hand, 1 tablespoon chopped fresh dill can be used in its place. We like this as a dip for veggies, but it also works well tossed with sturdy greens for salad.
