This trip, Guy Fieri's diggin' into hearty helpings -- both saucy and stuffed. In Los Angeles, there's El Salvadorian with a twist, like prime-time pupusas and an extra-meaty burger. In Oregon, a food cart in a motel parking lot is serving up authentic Indian. Plus in Pooler, Ga., a Puerto Rican joint is going crazy with a mofongo mashup and their take on a sloppy joe.
