Turn over bread (4)
I believe the answer is:
roll
This clue is a double definition.
'turn over' is the first definition.
('roll' can be a synonym of 'turn over')
'bread' is the second definition.
(roll is a kind of bread)
(Other definitions for roll that I've seen before include "Bakery product" , "Official register" , "cylindrical moulding" , "something on the drums" , "Move like a ball" .)
