Mexican Everyday by Rick Bayliss
This book is awesome. I've only started cooking very recently and I'm not any good at it, but using these recipes I've consistently gotten delicious, reasonably healthy food without much time or effort.
If you ever get a chance to eat at one of his restaurants in Chicago, do. The meal I had at Topolabampo was probably the best Mexican food I've ever had, quite a few meals in Mexico included.
