>>782431corn tortillas turn to shit after while.
they get crumbly so you will need to bring oil to reconstitute them to usable.
However:
Flour tortillas will stay good for quite a while in your pack. use parchment paper and a few paper towels and separate them and they wont get stuck together from humidity of being in a plastic bag. just burp the tortilla bag.
stuffings? crushed ramen with underwood chicken spread mixed with a pouch of chicken. and a pack of mayo.
