Good idea. And If you hit your local Dollar Tree they have it in little jars about half the size of the regular size. It's not bad tasting either. They also have a section for dried fruit nuts and trail mix in nice flat bags that will pack into smaller spaces. They even have $1.00 boxes of Tasters Choice instant coffee pouches.

Whatever you choose for your get home or bug out bags make sure you store the packages inside some decent quality zip lock bags . Mice can smell the food through whatever packaging material you have.
