Veteran cook given Asian bread (5)
I believe the answer is:
doyen
'veteran' is the definition.
(doyen is a kind of veteran)
'cook given asian bread' is the wordplay.
'cook' becomes 'do' (I've seen this in other clues).
'given asian bread' becomes 'yen' (I can't justify this - if you can you should believe this answer much more).
'do'+'yen'='DOYEN'
(Other definitions for doyen that I've seen before include "Senior member of a professional group" , "Top expert in a field" , "Prominent person in a particular field" , "Group's senior member" , "Respected expert" .)
