Roughly chop the walnuts and lightly toast them in a pan without fat. Remove and set aside.
Clean the chives and cut into fine rolls except for a few stalks. Mix with yoghurt, season with curry, lemon juice, salt and pepper.
Clean the Chinese cabbage, removing the stalk. Cut the cabbage crosswise into very fine strips. Peel the carrots and grate finely. Wash the apples, quarter them, core them and also grate finely. Layer with carrots and Chinese cabbage alternately in 4 glasses, drizzling with a little dressing again and again. Finish with a dollop of dressing, sprinkle with walnuts and garnish with chives.
