Opt to change dish (3)
I believe the answer is:
pot
'dish' is the definition.
'opt to change' is the wordplay.
'to change' indicates an anagram.
'opt' with letters rearranged gives 'POT'.
(Other definitions for pot that I've seen before include "It sometimes calls the kettle black" , "prize" , "Cooking vessel or slang marijuana" , "Shoot; pan" , "Slangy cannabis" .)
