3 or 4 Bean And Sausage Casserole

I am looking for a recipe my mother in law made for the holidays it was a 3 or 4 bean casserole with sausage in it that was sorta sweet and sour. You cook 1 pound sausage and used canned beans, brown sugar, vinegar and ketchup and some other ingredients. Bake for 45 min. to an hour I think. She made it for me because I loved it. I had the recipe but can’t find it. Does anyone have a recipe like this. It really brings back memories. Thanks a bunch, Leslie
