Setting: Early 1800's era with magic and a few bits of anachronistic technology.
1) I need a food that will hold up well all day on the stove. The one currently in the story I've described as a stew with various things thrown in without regard to their taste. I chose a stew over a soup because I wanted something that would be filling and basically be the equivalent of firehouse chili, in that it's something that sits on the stove all day staying warm. What ingredients would hold up to moderate heat without disintegrating into a mush and still be recognizeable? Off the top of my head, I remember mentioning slices of corn still on the cob and boiled eggs. Will those work? And what other ingredients would do the same? It won't really matter what real world cultures these ingredients come from since the city where this takes place is a melting pot of cultures although most of the inhabitants are vaguely Eastern European.

2) Magic and technology - not quite magitech - have enabled food preperation and preservation to reach levels that didn't exist in our actual early 19th century. Fast food, despite being most closely associated with the modern world, has existed since antiquity. Aside from various forms of paper, what other material could I use for takeout containers? Banana leaves? Palm leaves? What would work as cups. Bamboo? Clay? Lacquerware would be ideal, but it's not exactly cheap and wouldn't be something a hawker would give away for the price of a bowl of whatever food he was selling. Should I just sidestep the issue since it doesn't hinder the story at all?
