It very slightly remember a traditional meal here https://en.wikipedia.org/wiki/Locro You mix white corn, beans, pumpkin and whatever piece of meat you can grab, with some extra vegetables, bones more meat, sausage and whatever that is edible, and cook it for a long time (but usually less than a day), but it's always better the next day.

Thinking about it, I'd add an option to double the amount of some ingredients. For example some people like no onion, but others like a lot of onion.

Edit: In case you are curious, recipe by "Paulina Cocina" that usually has easy and tasty recipes (in Spanish) https://www.paulinacocina.net/receta-de-locro-argentino/9829

There are several Polish dishes that boil down to throwing whatever is edible into a single pot and boiling for hours. Bigos is mostly cabbage, gulasz is like very thin gravy, leczo has lots of red pepper and zucchini, jarzynowa (literally "vegetable soup") has no set ingredients at all.
