Skin the crumbly veal nut and cut diagonally to the grain into 12-16 slices (based on a nut of 1 kg), tap lightly by hand and place in a greased gratin dish. On top add finely chopped parsley, chives, shallots and mushrooms, mixed with salt, freshly ground pepper and oil. Cover and let stand for 2 hours. Then fold the veal slices and put them on skewers. Cook over a charcoal grill or in an oven grill until done, baste with Spicy Mustard Sauce (see recipe) and bring to the table.
Tip: As an alternative to fresh chives, you can also use the freeze-dried ones.
