Sunday entree (5)
I believe the answer is:
roast
'sunday entree' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for roast that I've seen before include "Be uncomfortably hot" , "cooked a certain way" , "Traditional dinner" , "Cook in oven or by exposure to heat" , "Give a telling off to - cook" .)
