Cheese put on a crossword setter's Japanese dish (7)
I believe the answer is:
edamame
'japanese dish' is the definition.
The definition suggests a singular noun which matches the answer.
'cheese put on a crossword setter's' is the wordplay.
'cheese' becomes 'edam' (Edam is an example).
'put on' says to put letters next to each other.
'crossword setter' becomes 'me' (referring to the person writing the clues).
'edam'+'a'+'me'='EDAMAME'
Can you help me to learn more?
(Another definition for edamame that I've seen is " type of bean".)
