Recipe: Kale Salad with Buttermilk Dressing and Pickled Onions "My grandmother always had a bottle of buttermilk in the fridge, and I love how it adds acidity and creaminess to this dressing." - Birmingham chef John Hall Beets, curly kale, hardcooked eggs, and tangy pickled onions make this salad a winner. Serve it as a side for brunch as Hall suggests, or add protein to make it a full meal.
