Turnover produced by prophet in South America (6)
I believe the answer is:
samosa
'turnover' is the definition.
(I've seen this before)
'prophet in south america' is the wordplay.
'prophet' becomes 'amos' (I've seen this before).
'in' is an insertion indicator.
'south' becomes 's' ('S' can be a synonym of 'south').
'america' becomes 'a' (common abbreviation - e.g. in organisation names).
's'+'a'='sa'
'amos' going within 'sa' is 'SAMOSA'.
'produced by' is the link.
(Other definitions for samosa that I've seen before include "Asian food" , "Indian fried pastry" , "exotic snack" , "Savoury turnover" , "Savoury Indian snack" .)
