Cold meal prison dished up (10)
I believe the answer is:
impersonal
'cold' is the definition.
(similar in meaning)
'meal prison dished up' is the wordplay.
'dished up' indicates an anagram.
'meal'+'prison'='mealprison'
'mealprison' is an anagram of 'IMPERSONAL'.
(Other definitions for impersonal that I've seen before include "Cool" , "Objective; disinterested" , "Aloof" , "Cold" , "Ignoring one's own feelings" .)
