Delish! Have tried with grapefruit, oranges, blood oranges, tangerines and/or mandarins. For the grapefruit I often have to cut out the core after I slice as it can be too tough. Used quick pickled Korean carrots and daikon which are always in my frig, arugula and/or spicy sprouts. Lots of pepper and good olive oil are key. Such a wonderful and quick winter salad!
