A side of meat, perhaps (4)
I believe the answer is:
team
'a side' is the definition.
(a side is a sporting team)
'meat perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'meat' with letters rearranged gives 'TEAM'.
'of' is the link.
(Other definitions for team that I've seen before include "Group or squad" , "Side; harness (horses)" , "Players united" , "Side in sporting event" , "A set of players forming one side" .)
