Leola root stew is a dish made from leola root.
Neelix was fond of making Leola root dishes while he served on Voyager for their high nutritional value, including Leola root stew.
In 2373, while Paris and Kim were trapped in the Akritirian prison, they became so hungry, they imagined even Neelix's Leola root stew would taste delicious. (VOY: "The Chute")
