This is something I created when I saw what was left from a bag of corn tortilla chips. Instead of throwing them out, I put them to good use, and I'm glad I did. This added a crunchy coating to chicken breasts, while the inside was nice and moist. You don't have to use corn tortillas if you don't want to. Use any style tortilla chip, or make your own. I've seen fish covered with a tortilla crust, but never chicken. Some call for eggs, flour, etc, but I just used Italian dressing for a marinade, and that was enough moisture to allow the chip mixture to stick. It also cut down on calories, because I used fat-free dressing. If you must use eggs, that's fine too. Play around with it, until you get what you like.
