melba toast like the ones in chex mix......geeeze your vision shakes when you bite and chew them.....pretty hard stuff.....lol
Hardtack. It is a hard cracker that can be broken into pieces and put in soup or a hot beverage. Soldiers in the American Civil War would eat this hard food.
I would say corn nuts.
