Man at the back of Aldi making bread (7)
I believe the answer is:
chapati
'bread' is the definition.
(chapati is a kind of bread)
'man at the back of aldi' is the wordplay.
'man' becomes 'chap' (term for a man).
'the back of' indicates one should take the final letters.
The last letter of 'aldi' is 'i'.
'chap'+'at'+'i'='CHAPATI'
'making' acts as a link.
(Other definitions for chapati that I've seen before include "I may be taken in with Indian" , "Unleavened bread of India" , "What Indian waiter might bring" , "Sort of bread" , "Indian food" .)
