Yes, that’s one of the ways I made up the contents of a lot of stuff in my bags.. gun shows.
There is always a decent survival preparedness type table and someone is always selling survival food so I take advantage of gun shows to stock up/upgrade, or rotate my bags contents.
I have several packets of these nutrition tables - claim is that seven of them provides the necessary nourishment for a day. They’re sealed, I have several in my car. There’s a gun show end of May our family is going to so will pick up a bunch of stuff then ... thanks for all the info.
