You live in Arizona and, therefore, are familiar with the standard corn tortilla. What may not be as familiar are pupusas, the Salvadoran take on the masa disks — they remind us of corn tortillas on steroids. At Salvadoreño, they offer up some of the meanest pupusas this side of the border, pumped to the max with ooey, gooey meat and veggie fillings. Our favorite pupusas are the revueltas, packed with pork, cheese, and beans, or the locoro and cheese, made with a South American flower bud similar in taste to asparagus or broccoli. Add a bit of mild red salsa and curtido, a vinegary cabbage slaw, to your pupusa and inhale. Then head to the register for another couple of pupusas. It's the right thing to do.
