This tasty sauce is a sure-(green)fire way to wake up your taste buds. I consider it a health food; you can actually feel the calories melt away as you eat it. And even if it isn't actually burning calories, it's a much better way to work up a sweat than using a stair master. It can be used as a dip, a condiment, or a sauce for dishes like chile rellenos or enchiladas. It is best when you put refridgerate the sauce for about an hour after preparation to allow the boiled tomatillos and peppers to cool down.
