Canned food is just damn stupid since you have to pack out the weight of a can if you're not a shitbird, and there's so much air/liquid in those cans they are heavy as fuck and pack terribly. Everything I mentioned above packs well and requires little to no 'packing out' besides the wrapper/baggie.
