Cecina (salted meat) and longaniza (sausage) at a fair-- with salsa and toppings at hand, of course.

All the makings of a cecina taco: tortillas, cecina (salted meat), longaniza (sausage), salsa, avocado, onions, radishes, and cheese.

I don’t know the answer, but Buzzfeed has prepared a handy quiz (“¿Puedes adivinar qué taco es con sólo verlo?”) about whether or not you can identify twelve types of tacos in Mexico.

I got two wrong answers, one because I identified the meat incorrectly and one because the name, “taco acorazado,” isn’t used here in Puebla. Street food names vary quite a bit from state to state and even town to town.
