Flatbread of India (3)
I believe the answer is:
nan
'flatbread of india' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nan that I've seen before include "Grandmother (informal)" , "Grandmother (colloq.)" , "Granny; bread" , "Grannie" , "Indian bread; grandma" .)
