Something to do with bread (5)
I believe the answer is:
slice
'with bread' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for slice that I've seen before include "poor golf shot" , "Cut into portions" , "share" , "Portion of pizza" , "shot in golf that goes astray" .)
