Dish from southern States -- hot one (5)
I believe the answer is:
sushi
'dish' is the definition.
(sushi is a kind of dish)
'southern states hot one' is the wordplay.
'southern' becomes 's' (abbreviation).
'states' becomes 'us' (abbreviation for the United States).
'hot' becomes 'h'.
'one' becomes 'i' (Roman numeral).
's'+'us'+'h'+'i'='SUSHI'
'from' acts as a link.
(Other definitions for sushi that I've seen before include "Japanese food" , "cold food" , "Japanese rice and raw fish dish" , "put away in Japan" , "Raw fish dishes" .)
