chicken enchilada's

I got a new cookbook: The Best of America's Test Kitchen 2007. (also check out their site.) It rocks. I tried these enchilada's last week, and they were SOOOO yum. Served it with rice and tortilla chips. A great make ahead meal for you, or a great meal to give to someone in need of one. :)
