Clean and wash the Brussels sprouts and cook in boiling salted water for about 15 minutes. Lightly roast almonds in a pan without fat, remove. Dab meat dry. Heat oil in a pan.
Fry the steaks in it for about 3 minutes on each side. Lightly crush the peppercorns. Season the meat with salt and spread peppercorns on top. Remove and keep warm. Drain the sprouts. Melt butter in a pot, toss sprouts and almonds in it.
Arrange steaks and Brussels sprouts on plates, sprinkle with parmesan. Potato balls taste good with it.
