Make a white sauce of the butter, flour, and cream. Add salt, pepper,
granulated bouillon dissolved in just a little hot water. Add the
mushroom soup. Saute the mushrooms in a little butter and add with the
chestnuts. Place in a buttered casserole and top with cheese. Place in
a 350 degree oven and heat for 20-30 minutes until cheese is melted and
dish is bubbly. Serve hot. (This is a huge casserole...great for
company or to take to a covered dish meal. For a single
family...prepare two casserole dishes and freeze one after fixing. Be
sure to thaw completely before reheating.) From a recipe collection by
