Side of meat, cooked (4)
I believe the answer is:
team
'side' is the definition.
(a side is a sporting team)
'meat cooked' is the wordplay.
'cooked' indicates anagramming the letters (letters cooked into a new form).
'meat' is an anagram of 'TEAM'.
'of' acts as a link.
(Other definitions for team that I've seen before include "See 22" , "A set of players forming one side" , "Group working in combination" , "Crew" , "Two or more working together" .)
