I do a lot of Mountain House as well. They make breakfast and dinner. I keep about 3-4 days worth on the long rides. Restock as needed.
Jerky, almonds, and power bar type energy stuff. During the day. Its easy to find and it quick energy.
Oh and one big one for me is some type of water flavor. I find nothing but water sometimes sucks.
So I bring water drink mixes like crystal light or what have you. Flavor. It helps me drink more.
