I believe I will try this by preparing it early in the morning according to the recipe but heating it up in a greased slow cooker. This would have the advantage of keeping it warm for a lunch time meal. Alternatively, for dinner, refrigerate mashed potatoes, and put them in the slow cooker around noon.
