Sanduíche de pernil

This Portuguese sandwich consists of shredded pieces of slowly roasted pork shoulder (pernil) which are placed on a crusty bread roll. The sandwich is typically enjoyed plain, but it can be enriched with mustard or cheese (ideally the Serra da Estrela variety). Sanduíche de pernil is mainly associated with Porto and the humble Casa Guedes restaurant, which is believed to prepare the best version of this hearty sanwich that first appeared at traditional Portuguese tascas bars.
