Peel and wash the potatoes and cut them lengthwise into slices. Peel and wash carrots and cut them diagonally into slices. Wash the rosemary, dab dry and chop roughly 2⁄3. Put the rest aside for garnishing.
Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3). Put vegetables, potatoes and rosemary on a fat pan. Drizzle with olive oil and mix everything. Sprinkle with salt, pepper and sugar.
Bake in a hot oven for about 45 minutes. Turn from time to time.
Meanwhile grate the cheese. Melt the butter. Chop the nuts. Mix butter, cheese, nuts, frozen herbs and breadcrumbs. Season with salt and pepper.
Wash the schnitzel and dab dry. Heat oil in a large pan. Sauté the meat in it for about 1 minute on each side. Season with salt and pepper.
Slightly push the potatoes and carrots together on the fat pan. Place the escalopes side by side on the fat pan and spread the nut mixture evenly on top. Bake in the oven at the same temperature for 8-10 minutes.
Arrange everything and garnish with the rest of rosemary sprigs.
