Red cabbage & carrot slaw

Cut the red cabbage in half and, starting on one side, use a vegetable peeler to slice it thinly into a large bowl. Add the grated carrots and sliced salad onions, then stir. In a small bowl, combine the yogurt, mayonnaise and cider vinegar, then pour over the coleslaw mixture. Grate the apple directly into the bowl and stir immediately to stop it from going brown. Just before serving, season with a pinch of salt. This is delicious alongside roast meats or in sandwiches.
