Credit us with cooking raw fruit & veg (8)
I believe the answer is:
crudites
'raw fruit veg' is the definition.
'credit us with cooking' is the wordplay.
'with cooking' is an anagram indicator.
'credit'+'us'='creditus'
'creditus' with letters rearranged gives 'CRUDITES'.
(Other definitions for crudites that I've seen before include "Raw vegetables served with a dip" , "Mixed raw vegetables served as an hors d'oeuvre" , "Sliced vegetables" , "Nibbles" .)
