Cook the lentils in boiling water for about 30 minutes until soft. Halve the chicory and cut out the stalk. Then cut into strips about the thickness of a finger. Wash the lamb`s lettuce and spin dry. Finely chop the onion and dill. Peel the carrot and grate finely. Cut the fish into bite-sized pieces. Mix the ingredients for the dressing with a hand blender. Mix the chicory, lamb`s lettuce, onion and shredded carrots and arrange on 4 plates. Spread the lentils on top, then place the smoked fish on the plates and sprinkle everything with dill. Drizzle with the dressing and serve.
