One cold dish served up with bread in the Gambia (6)
I believe the answer is:
dalasi
'bread in the gambia' is the definition.
(currency of the Gambia)
'one cold dish served up' is the wordplay.
'one' becomes 'i' (Roman numeral).
'cold dish' becomes 'salad' (I've seen this in another clue).
'served up' shows that the letters should be reversed in order.
'i'+'salad'='isalad'
'isalad' in reverse letter order is 'DALASI'.
'with' acts as a link.
(Other definitions for dalasi that I've seen before include "African ready" , "A bit of African mint" , "money overseas?" .)
