My husband and I were recently updating our emergency kit. (You know, the go bag they suggest you have with first aid supplies, blankets, flashlights, non-perishable food, etc. in case of an evacuation.) We live on an earthquake fault line and in a flood zone if the nearby dam breaks. Just looking for tips on program friendly foods that would work well. I was thinking of putting in some protein powder, but I don't want to put in an entire container, and I worry about it staying fresh if I only put in a partly used container. Has anyone done this? Or similar? Tips?
