I don't know if there is an original.
My grandmother made this for my grandfather 70+ years ago.
My mother made it for her family and now my wife and my sisters make it.
Like with so many recipes it varies greatly depending on what's on hand.
Sometimes we use ground beef or venison other times it's made with leftover pot roast, pork roast, and even chicken.
In spring it may get morel mushrooms or leeks and in fall it might be chicken in the woods. When peppers are scarce onions work well.
If you are low on bread serve it over noodles, rice, or mashed potatoes. Throw in some diced potatoes and you have a stew. Or thin it down and float some homemade dumplings on top.
Food can be exciting and if you like to cook, the possibilities are endless with almost any recipe.
Suggestions are always helpful and can be something you may not have thought of doing yourself. Some good and some bad.
I had a friend at work who added hot peppers to apple crisp, well it was...not so good.

Good Luck All
