Nopalitos remain strangely absent from many Mexican restaurants in the Valley, despite the fact that they are a ubiquitous ingredient in so many strains of Mexican cooking. But you can always find nopales at El Tlacoyo, Tempe's long-running, Mexico City-style restaurant. Most people go to El Tlacoyo to feast on specialties like barbecued lamb, but don't overlook a fresh-made huarache smothered in beans, crumbly white cheese, and topped generously with a bright, tangy and oniony salad of nopalitos. If you have not yet learned to embrace and love nopales, this simple, timeless dish might get you there.
