When it comes to Mexican sandwiches, restraint is not an ingredient. Consider the creations of Corona’s Galdino “Tortas” Neza, the largest of which, The Pumas contains a larder’s worth of ingredients, including a chorizo omelet, fried hot dogs, and a deep-fried chicken cutlet. The humongous hoagie calls to mind the adage: Never eat anything bigger than your head. Good as his tortas are there’s one sandwich you won’t find on the Mexico City born and bred chef’s menu: the cemita Poblana. That’s because it’s a specialty of Puebla. In fact I’ve never had a good version of this sandwich until I tried the Super Cemita Poblana at Villa Cemita in the East Village.
