Dish and cases played part (9)
I believe the answer is:
casserole
'dish' is the definition.
(I know that casserole is a type of dish)
'cases played part' is the wordplay.
'played' is an anagram indicator (letters playing around).
'part' becomes 'role' (eg a theatrical role).
'cases' is an anagram of 'casse'.
'casse'+'role'='CASSEROLE'
'and' acts as a link.
(Other definitions for casserole that I've seen before include "meal" , "Kind of stew" , "Stew-dish" , "(Food cooked in a) stewpot" , "Cook slowly" .)
