Cooked squid (8)
I believe the answer is:
calamari
'cooked squid' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for calamari that I've seen before include "Battered squid rings" , "Squid prepared as food" , "Mollusc" , "Mediterranean cooked squid" , "Squid served as food" .)
