Recipe by CCinSC

Put this together in the morning so can have a wonderfully different side dish that evening. Delicious companion with any beef, particularly steaks or roasts.

Absolutely sinful...I plan to keep this recipe the same as it is for company. The next time I make it for my family, I want to lighten it up by using less butter and cheese and substituting evaporated milk for the cream.
