Preheat the oven to 50 ° C. Wash, pat, plate and cut the veal escalopes. Halve the Parma ham and top the schnitzel with it. Pin the ham together with the sage with a toothpick.
Fry the schnitzel with the sage and ham side vigorously for 3 minutes. Season everything with salt and pepper, turn and fry for another 2 minutes and then keep warm.
Deglaze the roast with the broth and stir in the flakes of butter with a whisk. Pour the sauce over the schnitzel and serve immediately.
