Fish food? (7)
I believe the answer is:
sashimi
'fish food?' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sashimi that I've seen before include "food in Japan" , "Japanese dish of thinly sliced raw fish" , "Something of chef's" , "dish from Japan" , "possible accompaniment to 26 [SAKI]" .)
