I chop, as it's chopped nuts! (10)

I believe the answer is:

pistachios

'nuts' is the definition.
(I know this)

'i chop as it's chopped' is the wordplay.
'chopped' is an anagram indicator (letters chopped or smashed up).
'i'+'chop'+'as'+'its'='ichopasits'
'ichopasits' is an anagram of 'PISTACHIOS'.

I've seen this clue in The Telegraph.
