Elaborate spread (6)
I believe this is a double definition.
'elaborate' is the first definition.
(I know that elaborate can be written as expand)
'spread' is the second definition.
(I've seen this before)
(Other definitions for expand that I've seen before include "put on weight?" , "Become larger or more extensive" , "inflation" , "Make larger" , "Distend" .)
'elaborate spread' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for feast that I've seen before include "Grand meal" , "Huge nosh-up" , "Banquet or religious festival" , "Junket" , "Belshazzar's party" .)
