Peel and wash the carrots and cut them into diagonal slices. Peel and finely dice onions. Heat 2 tablespoons of oil in a pot and fry the onions in it. Season with salt, pepper and sugar.
Add the carrots and glaze. Deglaze with approx. 200 ml water and let it steam for approx. 8 minutes in an open pot. In the meantime, wash the cutlets, dab dry and cut in half crosswise. Cut a pocket into each cutlet and fill with 1 tablespoon of mustard.
Wash the sage and dab dry. Pluck the leaves from the stems. Put approx. 2 sage leaves in each cutlet. Season with salt and pepper. Heat the remaining oil in a frying pan and fry the cutlets in it on both sides at medium heat for about 5 minutes.
Add the remaining sage shortly before the end of the cooking time. Roast pine nuts at medium heat in a pan without fat until light brown. Stir the balsamic vinegar into the carrots. Arrange carrots and cutlets with sage on plates, sprinkle with pine nuts and garnish with parsley.
Baguette tastes good with it.
