Say beef or pork's to satisfy (4)
I believe the answer is:
meet
'to satisfy' is the definition.
(synonyms)
'say beef or pork's' is the wordplay.
'say' indicates a 'sounds like' (homophone) clue.
'beef or pork' becomes 'meat' (I've seen this in another clue).
'meat' sounds like 'MEET'.
(Other definitions for meet that I've seen before include "Join" , "Sporting encounter" , "Hunting gathering" , "Come face to face - it is fitting" , "sporting occasion" .)
