Brown bread (5)
I believe the answer is:
toast
I believe this clue is a double definition.
'brown' is the first definition.
(to brown something is to toast it)
'bread' is the second definition.
(toast is a kind of bread)
(Other definitions for toast that I've seen before include "Tribute (plus a clinking of glasses?)" , "Health drunk" , "meal component" , "It's found under marmalade and butter" , "making this pledge?" .)
