1 small cabbage
1 teaspoon sea salt
2 medium oranges
2-3 small tangerines or mandarins
3 tablespoons walnut oil
2-3 tablespoons red wine vinegar
Freshly ground black pepper
½ cup coarsely chopped walnuts
1. Discard any thick outer leaves of cabbage. Cut cabbage into quarters. Remove core and slice cabbage thinly. Place in a serving bowl.
2. Sprinkle cabbage with salt. Knead firmly with your hands for about 5 minutes; the cabbage will soften slightly and become milder in flavor. Leave 15 minutes. Place in a colander. Rinse under cold running water; drain.
3. Peel and segment oranges and mandarins or tangerines. Cut into small pieces over the bowl to catch the juices; discard seeds. Combine fruit and cabbage.
4. Whisk reserved citrus juice, oil, vinegar, and pepper until combined. Top with walnuts.
