If you've never cooked with tomatillos, this is a great place to start! This is a close adaptation from Steven Raichlen's "Big Flavor Cookbook" (great book!), and has been a favorite as it is fresh, easy to make, adaptable, and lower in calories and fats. I've served it on rice as well as in tortillas. It can be made ahead to reheat, and has contemporary feel in its fresh flavors. I like to use skinned, deboned chicken thighs, although Mr. Raichlen uses breasts.
