Pour 300 ml of warm water over the porcini mushrooms and leave to soak for about 1 hour. Cook spaetzle in boiling salted water for about 16 minutes. Peel shallots, possibly halve them. Clean mushrooms and halve them. Wash tomatoes, dab dry, quarter, seed and cut into cubes.
Pour the porcini mushrooms into a sieve, collecting the soaking water. Chop the porcini roughly. Heat oil in a pan. Fry the shallots for about 5 minutes. Wash the cutlets, dab dry, add to the shallots in the pan and fry for 4 minutes on each side. Season with salt and pepper, remove from the pan and keep warm. Put the porcini and mushrooms in the pan, fry them until they are hot and add the soaking water. Stir in tomato cubes and stock and bring to the boil. Season to taste with salt and pepper and thicken slightly with sauce thickener. Pour spaetzle into a sieve and drain.
