Sometimes prepared Noni's cocoa (2,8)

I believe the answer is:

on occasion

'sometimes' is the definition.
(I've seen this before)

'prepared noni's cocoa' is the wordplay.
'prepared' indicates an anagram.
'nonis'+'cocoa'='noniscocoa'
'noniscocoa' with letters rearranged gives 'ON OCCASION'.

(Another definition for on occasion that I've seen is " Sometimes".)

I've seen this clue in the Sydney Morning Herald.
