Wash the veal shank slices, dab dry and tie them round with firm kitchen string. Heat the oil in a pan and fry the slices vigorously. Season with salt and pepper and deglaze with wine and stock.
Cover and leave to braise for 1 1/2 hours. Peel onions and cut into slices. Peel garlic. Wash tomatoes, blanch hot and peel the skin. Cut tomatoes into quarters and remove seeds. Wash the herbs, dab dry and chop finely, except for a little garnish.
Add the onions, garlic, tomatoes and herbs 30 minutes before the end of the cooking time and braise. Season again and serve garnished with herbs. Delicious with baguette.
