American returned his cracked Japanese dish (5)
I believe the answer is:
sushi
'japanese dish' is the definition.
(type of Japanese food)
'american returned his cracked' is the wordplay.
'american' becomes 'us' (abbreviation for United States).
'returned' shows that the letters should be reversed in order.
'cracked' indicates an anagram.
'us' written backwards gives 'su'.
'his' is an anagram of 'shi'.
'su'+'shi'='SUSHI'
(Other definitions for sushi that I've seen before include "Raw fish dishes" , "'Dish of rice, vegetables and raw fish (5)'" , "Food from Japan" , "Asian food" , "oriental dish" .)
