I never get tired of peanut butter.
In my traveling days when I was going someplace where the vittles might be scarce like Somalia or Rwanda or western Pakistan I'd throw a large plastic jar of crunchy peanut in my shoulder bag. You could usually at least find some sort of local flat bread or naan or whatever, and maybe some local honey. Luck into some goat cheese and maybe some hummus and a man could get by for a couple weeks like that if he had to.
Yeah if you spread it wafer thin....I guess... 😁
