This is a child pragmatist's dream. Here's how something like this gets created. One day a kid was playing outside, not wanting to stop, but his mom called him to come inside. "You can't play again until you finish your whole lunch." The best way to get back to playing the fastest was to jam his chips into his sandwich and chomp away. He never realized he would change the world forever.
I think we've all experimented with chips in our sandwiches the same way we've all experienced with things in college... right? Dad, don't read this. But really, chips in the sandwich is a time-honored tradition. This gets a little wild with the nacho cheese Doritos. That's a pungent taste to mix with your PBJ. Anything to get back in the yard and play though, am I right?
