Chilaquiles are tortillas cut into strips, fried, and cooked in either a red or green sauce. Literally meaning "poor man's food", chilaquiles were undoubtedly invented as a way of using up leftover tortillas. They have evolved into a very versatile dish, with some rather sophisticated variations. The following version uses a red sauce; however a green sauce, such as the one given for Huevos al Albañil, below, is also very good. This is by KAREN HURSH GRABER.
