Offer sample of wasabi dish (3)
I believe the answer is:
bid
'offer' is the definition.
('bid' can be a synonym of 'offer')
'sample of wasabi dish' is the wordplay.
'sample of' indicates the answer is hidden within the clue (I've seen this in other clues).
'BID' is hidden within 'wasabi dish'.
(Other definitions for bid that I've seen before include "Take part in auction" , "Offer; command" , "Propose a payment" , "Tender (for work)" , "Attempt, offer" .)
