Speaking of cabbage, I suggest "sauerkraut" as a way to perhaps marginally increase the hunger reduction of cabbage, but more importantly to prevent cabbage from spoiling. Naturally-fermented sauerkraut (i.e. not just cabbage + vinegar) is capable of lasting for a long time, provided you can keep it away from oxygen (e.g. keep the cabbage submerged underwater) and let carbon dioxide escape (otherwise pressure buildup would destroy container). Would need some sort of storage container though...could maybe use a cooking pot + water. I don't have any experience with modding, but if someone is interested in implementing it, I'd be interested in seeing how it works.
