Wash the asparagus, cut off the woody ends. Cut the asparagus spears in half. Clean, peel and cut the kohlrabi into 16 sticks. Heat 1 tbsp. oil, fry the asparagus and kohlrabi in it. Season with sugar, salt and pepper.
Deglaze with broth and simmer for about 8 minutes. Take the vegetables out of the pan and let them cool down.
Wash the salad and drain well. For the vinaigrette, whisk lemon zest, juice, sugar, salt and pepper. Fold in 5 tbsp. oil in a thin stream. Season the vinaigrette to taste again. Wrap 2 pieces of asparagus and 2 pieces of kohlrabi in 1 slice of salmon each.
Arrange on plates with the salad and lemon slices. Drizzle with the vinaigrette. Bread tastes good with it.
