Meal just about finished? (6)
I believe the answer is:
repast
'meal' is the definition.
(repast can mean a meal)
'about finished?' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'finished?' becomes 'past' (I've seen this in another clue).
're'+'past'='REPAST'
'just' is the link.
(Other definitions for repast that I've seen before include "Something to eat" , "Prates about meal" , "A formal sort of meal" , "lunch?" , "A meal concerning time gone by" .)
