Large rich meals (6)
I believe the answer is:
feasts
'large rich meals' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for feasts that I've seen before include "Banquets or celebratory days" , "eats well" , "'Ceremonial, elaborate meals (6)'" , "Partakes of a banquet" , "Large rich meals" .)
