Season and herb the lamb and place in the fridge.
Using a small casserole, pour the olive oil and heat. Then gently fry the vegetables, then add the chickpeas and herbs and seasoning. Gently sweat it all and then add the tomatoes. Stir properly and let it reach boiling point. Then leave to simmer for 1 hour. You should not let the ragu dry too much; it still needs to have a shine, but not too wet.
In another pan, pour the rest of the olive oil and gently brown the shallots. Then add the red wine and some herbs. Let it reach boiling point. Add the veal jus, stir properly and place in the oven for an hour at 180 degrees C so as to gently poach the shallots.
In a frying pan, pour over a little olive oil and heat well. Seal the lamb thoroughly and place in the oven at 180 degrees C until it has reached the cooking degree of your preference. You will need to check it every 2 or 3 minutes.
