Indian food a man has at one (7)
I believe the answer is:
chapati
'indian food' is the definition.
(type of Indian bread)
'a man has at one' is the wordplay.
'a man' becomes 'chap' (term for a man).
'has' says to put letters next to each other.
'one' becomes 'i' (Roman numeral).
'chap'+'at'+'i'='CHAPATI'
(Other definitions for chapati that I've seen before include "Unleavened bread of India" , "I may be taken in with Indian" , "What Indian waiter might bring" , "Piece of bread (Indian)" , "Indian pancake" .)
