I don't want the food to take up more than one slot in my inventory. Also it should take long before it spoils, and have a decent caloric value.
Charred bread keeps long, but it's just grain and a small amount of satiety... yet it's easy to make and I guess it can stack into 64 items. Red meat stew has a very high satiety, but only one crock pot per slot, so no. Having to rely on finding food during the journey can slow you down a bit, but it's not that bad during summer/autumn.
What are your suggestions? I've finally crafted my backpacks so I can pack all the essentials when spring ends... eager to leave everything behind and migrate to a new home, closer to the equator!
