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' indicates putting letters inside.
'vessel cut' becomes 'shi' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'us' inserted inside '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" .)
