dear god, this is the greatest idea I've ever heard of! Dorito Burgers sound BOMB.

I am thinking about making my own with something like this:

Then I would brush it into a large glass pepper shaker.

Or if I feel lazy I may try and find a large electric pepper mill.
Something like this with a larger reservoir for the chips:

Of course if I could just get the pure stuff from Frito-Lay I would go that route i.e the stuff you scrap off your fingers with your teeth after you are done eating a bag; The Kind.

i definitely opened a bag of dorito's at work and found a nug of flavoring. my boss told me if i took a big bite of it, he'd buy pizza. i was pretty high so i saw no downside to this...
