What foods would you suggest that feed me the most, cost the least, can be stored for the longest and won't take up too much place (for size: 2 backpacks - 1 mostly filled with clothes..the top of it might be free; 2nd is about 30 liters (might exchange for a 50L, if I fix it) and two hands with two bags)) to be carried to the house in bumfuck nowhere?
Looking for "Just get a 10kg rice bag for this and that in chinese supermarket place and get a dry sauce that you mix up every time. doesn't take too much space to be carried" type of suggestions.
Thank you!
