Preheat oven to 375 degrees F. In a skillet, saute the mushrooms and shallots in the margarine. Add the brandy and herbs and cook about 4 minutes. In a bowl, combine the cream, egg and egg yolks. Fill the pie crust with the cheese, place the mushrooms and shallots on top, and pour the cream and egg mixture over all. Bake for about 30 minutes, longer if necessary.
