Like toast not fit for consumption making one fed up (7,3)
I believe the answer is:
browned off
'one fed up' is the definition.
(I've seen this before)
'like toast not fit for consumption' is the wordplay.
I cannot really understand how this works, but
'toast' could be 'brown' (to toast something is to brown it) and 'brown' is present in the answer.
'not' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
This explanation may well be incorrect...
'making' is the link.
Can you help me to learn more?
(Other definitions for browned off that I've seen before include "Annoyed" , "Cross" .)
