Lupin or Lupini Beans are yellow legume seeds of the lupinus genus plant, most commonly the Lupinus luteus or Yellow Lupin, and were once a common food of the Mediterranean basin and Latin America. Today they are primarily eaten as a pickled snack food. The Andean American variety of this bean, Lupinus mutabilis, was a food widespread during the Incan Empire. Lupins were also used by Native Americans in North America, e.g. the Yavapai people.
