I find that oatmeal doesn't last long enough. A local store has bulk foods with a 5 grain cereal that lasts much longer. I add chopped dates for a sweetener and several kinds of nuts and seeds. A bit of powdered milk helps, too. I prepackage it in meal sizes in quart freezer bags. Just add boiling water and let it sit 6 or 8 min. The only dirty dish is a spoon.
