Dish, Greek, Dee cooked (8)
I believe the answer is:
kedgeree
'dish' is the definition.
(kedgeree is a kind of dish)
'greek dee cooked' is the wordplay.
'cooked' is an anagram indicator (letters cooked into a new form).
'greek'+'dee'='greekdee'
'greekdee' is an anagram of 'KEDGEREE'.
(Other definitions for kedgeree that I've seen before include "Fish/rice/egg dish" , "Rice dish with boiled eggs and flaked fish" , "Fish dish out of reed geek" , "Dish of rice, smoked fish and eggs" , "Indian rice dish" .)
