Row of houses supplied by foreign caterer (7)
I believe the answer is:
terrace
'row of houses' is the definition.
(I've seen this before)
'foreign caterer' is the wordplay.
'foreign' is an anagram indicator (foreign order of the letters).
'caterer' with letters rearranged gives 'TERRACE'.
'supplied by' acts as a link.
(Other definitions for terrace that I've seen before include "Row of usually identical and connected houses" , "Row of houses joined together" , "From which spectators watch" , "flat roof" , "Balcony" .)
