Indian fare like nothing mother's served up (6)
I believe the answer is:
samosa
'indian fare' is the definition.
'like nothing mother's served up' is the wordplay.
'like' becomes 'as'.
'nothing' becomes 'o' (looks like zero - 0).
'mother's' becomes 'mas' (ma is a kind of mother).
'served up' shows that the letters should be reversed in order.
'as'+'o'+'mas'='asomas'
'asomas' reversed gives 'SAMOSA'.
(Other definitions for samosa that I've seen before include "Small Indian cake of meat or vegetables" , "exotic snack" , "Indian dish" , "Small Indian pastry of meat or vegetables" , "tasty snack" .)
