Vegetable processed to get cure (9)
I believe the answer is:
courgette
'vegetable' is the definition.
(courgette is a kind of vegetable)
'processed to get cure' is the wordplay.
'processed' indicates an anagram.
'to'+'get'+'cure'='togetcure'
'togetcure' anagrammed gives 'COURGETTE'.
(Other definitions for courgette that I've seen before include "Small marrow" , "Small green vegetable" , "One of the vegetables" , "this could supply kitchen" , "Type of vegetable marrow" .)
