Side of fresh meat (4)
I believe the answer is:
team
'side' is the definition.
(thesaurus)
'fresh meat' is the wordplay.
'fresh' indicates anagramming the letters.
'meat' is an anagram of 'TEAM'.
'of' is the link.
(Other definitions for team that I've seen before include "Working animals" , "Group working together" , "Two or more working together" , "Side in sporting event" , "People working together" .)
