A few years ago, I was watching an episode of "Thowdown" with Bobby Flay on the Food Network, and the episode centered around a little hole in the wall place in New Mexico that was famous for their green chile cheeseburgers. As the show unfolded, the owner of the little hole in the wall described the basic ingredients (fire roasted chiles and caramelized onions) in his famous burgers, but not the cooking process, and it became pretty obvious this would be an easy thing to duplicate.
