Apricots are best soaked overnight covered with water. Select the kale and wash thoroughly. Bring water to the boil. Bring the kale to the boil briefly, drain, allow to cool slightly and cut into large pieces.
Onions peel and cut into slices. Fry pork cheek briefly in a pan without fat. Add kale and half of the onions. Pour in broth, bring to the boil. Cover and cook on low heat for 45 minutes.
Drain the apricots and add them 15 minutes before the end of the cooking time. Heat the fat in a frying pan and sauté the remaining onions. Remove the pork cheek from the cabbage. Season the kale with mustard, salt and pepper.
Cut the meat into slices. Arrange the kale with the pork cheek and the fried onion slices together. Sprinkle meat with pepper to taste.
