Dish up (5)
I believe the answer is:
serve
'dish up' is the definition.
(I know that dish up can be written as serve)
This is all the clue.
(Other definitions for serve that I've seen before include "Commence play in tennis" , "Minister to" , "Be of use to - wait on" , "Be adequate; put ball in play" , "Milton 'They also . . . . . who only stand and wait'" .)
