Cherished island spot is cultivated to yield veg (6,4)

I believe the answer is:

petits pois

'veg' is the definition.

'cherished island spot is cultivated' is the wordplay.
'cherished' becomes 'pet'.
'island' becomes 'i'.
'cultivated' is an anagram indicator.
'spot'+'is'='spotis'
'spotis' with letters rearranged gives 'tspois'.
'pet'+'i'+'tspois'='PETITS POIS'

'to yield' is the link.

I've seen this clue in The Independent.
