Vegetable a chore — Kit harassed (9)
I believe the answer is:
artichoke
'vegetable' is the definition.
(type of vegetable)
'a chore kit harassed' is the wordplay.
'harassed' indicates anagramming the letters.
'chore'+'kit'='chorekit'
'chorekit' is an anagram of 'rtichoke'.
'a'+'rtichoke'='ARTICHOKE'
(Other definitions for artichoke that I've seen before include "Edible thistle-like bud" , "See 26" , "Plant with edible flower heads" , "Jerusalem, perhaps" , "vegetable's served?" .)
