German toast (6)
I believe the answer is:
prosit
'german toast' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for prosit that I've seen before include "Drinking salutation" , "Good luck to you" , "Bottoms up (in Germany)" , "... [good-health]" , "Good health! Cheers!" .)
