Survival food with a long shelf life ( part of my "grab in case of war" backpack)

 Call me old-fashioned, but when it comes to survival food, I don't trust these new inventions with dry food, and I prefer the good old canned food. Canned meat and lentils - cook quickly, do not take up much space in the backpack, and provide the necessary protein and carbohydrates to withstand the load.
