Bantan

From Memory Alpha, the free Star Trek reference.

Bantan is a spicy vegetable native to the Delta Quadrant. The pink portions of bantan are unsuitable for consumption.

Kes grew bantan in her hydroponics bay aboard USS Voyager. (VOY: "The Cloud")

Unless the pink portions of the bantan provided flavor to the meal, it is interesting that Neelix would leave it on, even if it was to be a garnish.
