Heroic task: cooking vegetables (10)

I believe the answer is:

artichokes

'vegetables' is the definition.
(artichoke is a kind of vegetable)

'heroic task cooking' is the wordplay.
'cooking' is an anagram indicator (cook can mean to falsify or distort).
'heroic'+'task'='heroictask'
'heroictask' anagrammed gives 'ARTICHOKES'.

(Another definition for artichokes that I've seen is " vegetables".)
