Cut the turkey breast into thin strips. Clean, wash and slice the mushrooms. Peel and finely chop the shallots.
Melt the margarine in the pan and sweat the shallots in it. Fry the turkey breast strips briefly. Add the mushrooms and continue frying. Take everything out of the pan and keep warm.
Deglaze the roast with the stock. Stir in the herb cream cheese and let it melt. Bring to the boil and sprinkle in the sauce thickener. Season with salt, pepper and lemon juice.
Put the meat and mushrooms in the sauce and sprinkle with chopped parsley. Rice and salad go well with it.
