Repast (4)
I believe the answer is:
meal
'repast' is the definition.
(I know that repast can be written as meal)
This is the entire clue.
(Other definitions for meal that I've seen before include "dinner, maybe" , "Edible part of grain or pulse" , "Breakfast, dinner or supper" , "Food taken at a particular time" , "Supper, e.g." .)
