Tea bags butter bread (7)
I believe the answer is:
chapati
'bread' is the definition.
(chapati is a kind of bread)
'tea bags butter' is the wordplay.
'tea' becomes 'chai' (I've seen this before).
'bags' indicates putting letters inside (bag can mean secures or steals).
'butter' becomes 'pat' (a pat can mean a lump of butter).
'chai' placed around 'pat' is 'CHAPATI'.
(Other definitions for chapati that I've seen before include "Unleavened bread of the subcontinent" , "Indian food" , "Sort of bread" , "Piece of bread (Indian)" , "Unleavened bread of India" .)
