Boil eggs hard for 10 minutes. In the meantime, clean and wash the salad and celery stalks. Drain salad and pluck into bite-sized pieces. Cut the celery into thin slices.
Wash the cucumber, peel and slice as desired. Clean, wash and quarter the tomatoes and mushrooms. Wash herbs, dab dry and cut finely, except for a few stems for garnishing.
Quench the eggs cold, peel and quarter them. Roll up slices of smoked salmon ham and carefully cut into slices. Put yoghurt and mustard in a bowl and mix. Add finely chopped herbs and stir in.
Season to taste with curry, salt and pepper. Arrange prepared vegetables on plates. Place egg quarters and salmon ham rolls on top. Add yoghurt sauce and garnish with a bouquet of herbs.
Roasted rye toast is delicious with it.
