Shit on a Shingle

My dad was in the army for 24 years and my mom use to make this for him. I love the stuff. The navy uses chipped beef but I prefer the hamburger version.
Here is an official U.S. Army recipe for SOS:
CREAMED BEEF ON TOAST (SOS)
1/2 lb. ground beef
1/4 tsp. salt
1/4 tsp. pepper
4 tbsp. sifted flour
1 cup evaporated milk
1 cup water
2 tbsp. butter
Brown ground beef in its own fat. Remove excess fat and save for making roux. Season with salt and pepper. To make roux, place 2 tbsp. reserved fat in double broiler or heavy pan. Slowly add sifted flour, stirring constantly over low heat until thoroughly blended. Cook for five minutes. Do not brown. Combine milk and water. Add butter and scald (not burn) in double broiler or heavy pan. Add roux to scalded milk, stirring constantly until thoroughly blended. Add meat mixture and cook about 10 minutes, or until desired consistency. Serve on toast.

WWII troop slang for chipped beef on toast, frequent fare in mess halls.

A basic army entree, consisting of some form of meat on a form of bread.

Hamburger meat with sauce on toasted bread (something like a Sloppy Joe's but not in a bun--but on white toast). Quite distinct from foreskins on toast which is creamed chipped beef. Nautical term.

1) This meal is served in nearly every American home for the days following Thanksgiving. Two slices of bread covered with turkey gravy and pieces of meat. It is usually accompanied by mashed potatoes.
2) The United States Military adopted the term Shit on a Shingle for its WWII chipped beef an cream.
