Heat 1 tablespoon of oil in a frying pan. Fry the Leberkäse for about 2 minutes on each side. Take out and drain on kitchen paper.
For the vinaigrette, mix vinegar, mustard, salt, pepper and honey. Fold in 2 tablespoons of oil until creamy.
Halve Leberkäse, then cut crosswise into strips. Cut mountain cheese first into slices, then into strips. Clean and wash the bell peppers and cut them into long, thin strips. Peel onions and cut into rings.
Wash the chives, dab dry and cut into small rolls. Mix all salad ingredients with the vinaigrette. Leave to infuse for approx. 30 minutes.
Season the salad again with salt and pepper. Lye pastry tastes good with it.
