Divide the load by 2. For an example I almost always pack my LL Bean hammock, several fishing rods and a large camera bag. Food goes into those heavy canvas bank money bags separated into breakfast, lunches and dinner. This avoids lots of hunting and confusion. Trail snacks go into your pockets or horn bags on your saddle.
Frozen grub goes into a thinsilate collapsible cooler.
Meat that is frozen and then double wrapped in newspaper will stay frozen for up to five days and then keep for a couple of days more. Eggs are kept nestled in the grain in the bottom of the panniers in their cartons. In a word or two - freedom and distance. You are only limited by the amount of food you can pack. Plus you don't have to see the same thing twice - going and coming.
