When it comes to quick Mexican eats, the taco immediately comes to mind. But Mexico has serious sandwich game with both the tortaworld and its cousin, the imposing, gut-busting, incredible cemita.

A specialty of Puebla, the cemita is distinguished by its slightly sweet, eggy sesame-seed roll, its neat layers of fillings, and its shredded quesillo cheese.

Let's break it down.

The bread. Whereas tortas come on a white roll called a telera, the cemitas use a round, rich, eggy, roll. A proper cemita roll is soft in the middle, just a little crisp on the outside and sturdy enough to stand up to a pile of toppings.

The filling. Think refried beans, shredded white cheese, avocado, tomato, lettuce, chipotle chilies, onion, mayo, and the fresh herb papalo—a sort of cross between arugula and cilantro. All those together define the cemita, but that's before you even get to the main event: Do you want fried chicken? Carnitas? Lengua? Carne asada? You can have them all.

Where to get them:
