Has any of you tried mixing some unheated water with your dehydrated dinner items around lunchtime to give them a head start on rehydrating? I hear complaints about some things that don't rehydrate easily (ground beef, corn, peas) and it seems like giving them a few hours head start on rehydrating would help. Of course it would require an extra container, but a pint-sized plastic mayo jar doesn't weigh much. Too much hassle? Good idea? Thoughts?
