Mixing all different kinds of citrus with brussels sprouts, olives and dates creates a delicious and unusual winter salad. Slideshow: Cabbage Recipes
Using a sharp knife, peel the grapefruit and mandarin oranges, removing all of the bitter white pith. Working over a large bowl, cut in between the membranes and release the sections into the bowl. Squeeze the juice from the grapefruit into the bowl; you will need 1/4 cup. Add the kumquats, brussels sprouts, olives, dates and olive oil and season with salt and pepper; toss to evenly coat. Serve.
