Dice cheese and ham very finely. Mix with nuts. Wash the meat, dab dry and cut a pocket with a sharp knife. Spread the cheese filling in it and fix it with skewers.
Clean and wash broccoli and cut into florets. Heat the oil in a large pan. Brown the escalopes in it all around. Fry over a low to medium heat for 10-12 minutes, turning over.
Season with salt and pepper.
Keep the chicken escalope warm. Deglaze frying fat with 1/4 l water, stir in broth and bring to the boil. Refine with crème fraîche and boil down a little.
Cover the broccoli and cook for about 5 minutes in a little boiling salted water. Drain. Season sauce to taste and arrange everything. Garnish with chervil. Serve with mashed potatoes.
Drink tip: cool rosé wine, e.g. a Corbières.
