Travelling US area, Turk delivers cabbage dish (10)
I believe the answer is:
sauerkraut
'cabbage dish' is the definition.
'travelling us area turk' is the wordplay.
'travelling' is an anagram indicator.
'us'+'area'+'turk'='usareaturk'
'usareaturk' is an anagram of 'SAUERKRAUT'.
'delivers' is the link.
(Other definitions for sauerkraut that I've seen before include "Shredded cabbage fermented in brine" , "German course" , "German pickled cabbage" .)
