Well, with enough heat you can dry most things. I sliced up a half price roast and turned it into a sort of biltong/jerky in the kitchen oven over night on the lowest setting, with the door open, and some of those slices were a touch more than half an inch thick when fresh.
Thicker slices make it less of a snack food since it will be slower to pick up atmospheric moisture and its easier to carry, but harder to eat in the hand.
