In a saute pan with the olive oil, sweat the leeks and brown the mushrooms lightly. Add the sherry and reduce. Add the rice and saute for 2 minutes.
In three stages, stir in the chicken stock. Continue to stir during the process of adding the stock. When all the stock is absorbed, taste the rice for doneness. If the rice still has a bite to it, stir in more stock and continue to cook.
Stir in the Parmesan and the parsley. Season and serve.
