Grilled bread for health? (5)
I believe the answer is:
toast
This clue is a double definition.
'grilled bread' is the first definition.
(I've seen this before)
'health?' is the second definition.
(I've seen this before)
'for' is the link.
(Other definitions for toast that I've seen before include "Cook by radiant heat" , "Formally drink a health" , "Brown by radiant heat" , "Raise a glass to (someone)" , "Drink to the healt of" .)
