Clean mushrooms with a vegetable brush. Remove the skin from the onions. Cut mushrooms and onions into cubes. Heat only 20 g of the clarified butter. Sauté vegetable cubes in it for three minutes. Cut cheese into cubes. Rinse parsley and chop finely. Stir into the mushrooms and season with salt and pepper.
Spread cheese and mushroom mixture evenly over cutlets, roll up carefully and pin with roulade skewers. Season meat rolls with salt and pepper. Heat remaining clarified butter in a frying pan. Brown roulades in it on all sides over medium heat. Cover with lid and continue to cook in the closed container for six to eight minutes until the cheese has melted.
The involtini is delicious with a zucchini and strawberry gratin.
Tip: Zucchini are a type of squash and therefore low in calories, rich in vitamins and easy to digest – just the thing for a light meal!
