Beet and Citrus Salad with Pinenut Vinaigrette Beets and citrus are a classic combination. This salad combines grapefruit, orange, roasted beets, and bit of arugula for some peppery kick. Nuts, in this case pine, go great with beets, and a vinaigrette made with sherry vinegar, shallots, walnut oil, and a touch of agave nectar sweetens the whole thing.
