Roach food creation question

[MrWhite]

what equipment does everyone use to create their roach chow. I know what to put into the chow, I just want to know the easiest way to grind it up. I was thinking of purchasing a small coffee grinder to grind the dry dog chow. Any other ideas?

Thats what most use. I have not had any money to get one so Idouble bag in zip lock baggies and pound with a hammer
