Fare from Japan or America aboard vessel cut (5)
I believe the answer is:
sushi
'fare from japan' is the definition.
(fare can mean food)
'america aboard vessel cut' is the wordplay.
'america' becomes 'US' (United States).
'aboard' means one lot of letters goes inside another.
'vessel cut' becomes 'shi' (I can't justify this - if you can you should give a lot more credence to this answer).
'us' put within 'shi' is 'SUSHI'.
'or' is the link.
Can you help me to learn more?
(Other definitions for sushi that I've seen before include "'Dish of rice, vegetables and raw fish (5)'" , "oriental dish" , "cold food" , "Japanese food" , "Rice, seafood cuisine" .)
