Sandwich (Italian) fed Kansas city (7)
I believe the answer is:
wichita
'kansas city' is the definition.
(Wichita is a city in Kansas)
'sandwich italian fed' is the wordplay.
'fed' indicates a hidden word (the clue has been 'fed' the answer).
'WICHITA' is hidden within 'sandwich italian'.
(Other definitions for wichita that I've seen before include "US city" , "Kansas city" , "city in America" , "place in Kansas" .)
