Chop the cabbage very thinly and put it in a large salad bowl. Add the other ingredients and mix them lightly. Refrigerate the salad and serve cold. The salad should be consumed within 2 to 3 days. Instead of mayonnaise and mustard you could use 250gr fresh cream whisked lightly. (It is called Christmas salad, because the pomegranate used on Christmas day is one of the ingredients required for its preparation)
