Neelix was fond of making Leola root dishes while he served on USS 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")
When most of the crew began to have unusual nightmares due to contact with the dream species, Neelix said that he had a dream he was drowned in a pot of "perfectly seasoned" Leola root stew, at which B'Elanna Torres noted that that would be a true nightmare. VOY: "Waking Moments")
When Paris was confined to the brig in 2375, Neelix was permitted only to bring him "basic nutrition", which included Leola root stew – much to Paris' distaste. (VOY: "Thirty Days")
