Pork Rinds. Just plain old Pork Rinds will do. My nearby Alid's sells these super cheap plain Pork Rinds by Clancy's that are really good ... they make perfect dipping vehicles for about anything, so you could make your own Primal version of nachos out of them if you'd like.
Loose meat is always good, easy to make ham and a cheese wraps. I'll try to think of some more, but those are my two go to snacks: Pork Rinds and Meat/Cheese wraps.
