Once everything is cooked until soft, mix in the cream, season to taste and finish with the butter.
Spread 4 pieces of de-barked toast or tramezzini with Glinitzer`s hazelnut nougat and stack 3 layers on top of each other twice.
Bread this package like a Wiener Schnitzel and fry in a pan in plenty of oil on both sides. Cut into four triangles each and arrange in the soup.
