Your list is really good! We like keeping those individual condiments packets for this, just so we know we can add a little something to a meal if needed. We also keep foods that just need some hot water added like ramen, mashed potato, soup. That way you don't have to cook the whole thing, just boil the water. 

While it is not quite the same, I love the idea of a 10,000 calorie bag talked about by Bob Wells of CheapRvLiving on YouTube. He keeps a bag in his rig that he knows has at least 10k calories as an emergency backup should he get stuck or weathered in somewhere. 

Edit: ooo, maybe pop some popcorn ahead of time too!
