Died beef simmered in a velvety white sauce or Béchamel is the definition of Creamed Chipped Beef aka SOS. It has become our Christmas Morning Meal, a tradition brought from Pam's youth.History of the name SOS in our house: While serving in the Navy, creamed chipped beef was a staple on the ship for breakfast. Not all of the Navy cooks took the care to always make the sauce smooth and creamy and the crew began to nickname it "Shit on a shingle" as it was always served on burnt thin toast. Grandpa Campbell accidentally said it one day when I was little and it has been SOS ever since (to me, at least).
