Tube grubs.
Tube grubs are a larva-like organism eaten live as a delicacy by the Ferengi. It seems that, traditionally, tube grubs are to be served chilled (DS9: "The Nagus").
- According to a line cut from DS9: "Family Business", tube grubs can also be served with millipede sauce.
Joseph Sisko considered offering Cajun-style tube grubs at his resturant, Sisko's, in New Orleans in 2372. Although Joseph Sisko said he would have to cook them, which Nog found odd. (DS9: "Homefront")
Ishka offered to make tube grubs for Quark and even pre-chew them, when he visited her in 2373, but Quark stated he'd never liked her grubs. (DS9: "Ferengi Love Songs")
Benjamin Sisko once cooked pureed tube grubs for his son and Nog in late 2373. Jake enjoyed them until he found out what they were. (DS9: "Blaze of Glory")
Background
Food offered to Captain Picard.
Tube grubs resemble the food eaten by Starfleet Command personnel while under the control of the alien neural parasites in TNG: "Conspiracy" because both props used meal worms.
