"This Salvadoran pupuseria with two Maryland locations and another in Falls Church, Virginia is one of the region’s cheapest options for masa stuffed with cheese and other ingredients for under $3. There are traditional pupusas, like revuelta, as well as offbeat options like a ham and cheese pupusa. The spot also has a huge menu of other affordable options, from soups to grilled platters. For more affordable pupuserias, go here." - Tierney Plumb
