What’s a pupusa? It’s a Salvadoran specialty, a thick tortilla that’s stuffed, then grilled, with refried beans, cheese, and chicharrón. Pupusas are served warm with a side of cabbage slaw and salsa—it’s a little taste of Central America in Charlotte. (The name “El Pulgarcito,” which means “little thumb,” refers to El Salvador’s status as the smallest country in Central America.)
