In the meantime, add the cream and herbs, except for a tablespoon, to the stock, bring to the boil and add the sauce thickener while stirring. Bring to the boil again briefly and season to taste with salt and pepper. Heat the fat in a frying pan and fry the mushrooms, turning them, add broccoli and warm them up while tossing.
Cut the meat into slices and arrange on a plate with vegetables and sauce. Serve garnished with herbs and, if desired, with a tomato rose. Serve the rest of the sauce separately.
