Sumptuous suppers (6)
I believe the answer is:
feasts
'sumptuous suppers' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for feasts that I've seen before include "Partakes of a banquet" , "'Ceremonial, elaborate meals (6)'" , "Large rich meals" , "religious celebrations" , "Sumptuous meals" .)
