Clean the salad, wash and drain well. Clean, peel and wash the kohlrabi, grate coarsely. Radishes clean, wash and cut into thin slices. Cut cheese into sticks. Wash chives, dab dry and cut into small rolls.
Mix mustard, 4 tablespoons of vinegar, salt, pepper and sugar. Beat the oil in a thin stream. Stir in chives and season to taste again. Mix the salad ingredients and arrange on plates. Boil 2 litres of water in a large pot of water.
Add 6 tablespoons of vinegar. Turn back the temperature. Beat the eggs one by one in a cup and let them slide into the water. Cook eggs in boiling water for about 4 minutes. Take out with a skimmer and let them drip off on kitchen paper.
Arrange the eggs on the salad and sprinkle with the vinaigrette. Bread is delicious with it.
