Discover that man wants minute dish from Japan (5)

I believe the answer is:
sushi
'minute dish from japan' is the definition.
I can't judge whether this defines the answer.
'discover that man' is the wordplay.
'discover' becomes 'sus' (as in sussing something out).
'that man' becomes 'hi' ().
'sus'+'hi'='SUSHI'
'wants' acts as a 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)'" , "Raw fish dishes" , "Oriental food" , "Fated" , "Japanese food" .)
