Make a white gravy with mushrooms.





Or this is actually a spaghetti sauce from Betty Crocker but would also be good over your chicken.





Okay I can't find the recipe bit it is pretty much white gravy, with sliced msuhrooms and fresh lemon juice squeezed in.





Or an alfredo sauce, or a of just melted down cream cheese with some milk and seasonings.
White Sauce (just mix heavy cream with parmesan cheese and add some lightly sauteed mushrooms, and a little garlic.)
