Goober (6)
I believe the answer is:
peanut
'goober' is the definition.
(I know that goober can be written as peanut)
This is all the clue.
(Other definitions for peanut that I've seen before include "Dry-roasted or salted snack item" , "Seed also known as a goober" , "Edible seed of Arachis hypogaea" , "Leguminous seed eaten as snack or butter" , "Eat pun for the hard fruit" .)
