Wash the chervil, dab dry and pluck the leaves from the stems. Peel carrots and cut them into long sticks. Wash the meat, dab dry and season with salt and pepper. Melt fat in a pot and fry carrots in it. Deglaze with vinegar, season with salt and sugar.
Stir in 1/3 chervil leaves. Keep carrots warm. Heat oil in a pan. Cover the meat with 1/3 of the chervil leaves and fry for about 3 minutes on each side. Arrange on plates and garnish with the last 1/3 of the chervil leaves
