Clean the Chinese cabbage, cut into strips, wash and drain well. Sprouts also wash and drain. Clean, wash and slice the carrots lengthwise, then cut them into rhombs. Peel and finely chop the onion. Heat the oil in a pan and fry the onions in it until transparent. Add carrots, honey and vinegar, season with salt and pepper and simmer for three to four minutes.
Mix warm carrots with Chinese cabbage and sprouts and let cool off. In the meantime, stir sour cream and horseradish with milk until smooth for the sauce. Season to taste with salt and lemon juice. Cut the cress from the bed and stir it in, except for a little bit for sprinkling. Arrange the salad in a bowl and pour the sauce over it. Sprinkle with remaining cress and serve garnished with parsley
