Lentils are a high-protein pulse that is dried and then soaked and cooked before eating. Lentils vary in size, and are sold in many forms, with or without the skins, whole or split. Canada is now the world's largest exporter of lentils to the global marketplace, selling to over 100 countries each year. The most commonly grown lentils are the large green "Laird" and the red lentil.
