Either way, it is Indian bread (4)
I believe the answer is:
naan
'indian bread' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for naan that I've seen before include "Indian food" , "Slightly leavened bread" , "Indian type of bread" , "Indian bread shaped like a teardrop" , "foreign food" .)
