Feijoada is a main staple of the Brazilian diet and the national dish, especially in Rio de Janeiro. It is a feast of stewed beans in a pork or beef gravy, and several cuts of meat with the more traditional ones containing almost every part of the pig and sausages (Linguiça).

It is accompanied by farofa (cassava flour), shredded kale, rice, and oranges which are meant to help with digestion. It was adapted from the food of slaves, and is now regularly eaten for lunch on Saturdays or Sundays and at special events for instance the Rio carnival.
