I believe the answer is:
emancipate
'free' is the definition.
(thesaurus)
'meat-pie can be served' is the wordplay.
'be served' indicates anagramming the letters.
'meat'+'pie'+'can'='meatpiecan'
'meatpiecan' is an anagram of 'EMANCIPATE'.
(Other definitions for emancipate that I've seen before include "Free from restrictions" , "Free from slavery" , "setting free" , "Liberate" , "release" .)
