Clean, wash and drain the salad. Cut the cress from the bed and chop into small pieces. Mix cream cheese, cress, honey and mustard. Chop the walnuts. Put 1 tablespoon aside. Fold half the walnuts into the cream.
Season to taste with salt, pepper and sugar. Spread the cream on the turkey breast slices (approx. 1 teaspoon per slice) and roll up. Mix vinegar with 1 tablespoon of water. Season with salt, pepper and sugar, fold in oil and stir in the other half of the walnuts.
Arrange salad and rolls, sprinkle with dressing and sprinkle with remaining walnuts.
