Something my dad used to make waaay back wheen he was young and in the army - An all-in stew.
Basically, anything that was left in the kitchen at camp was thrown in. Peas, Gravy, carrots, mars bars, corn flakesl anything. Aparrently, the end result when it was all done with quite nice, the mars bars melted down into the stew and added a lot of flavour.
Maybe one day... I'll give it a try.
