Use lime, but not all of it, to make healthy breakfast, maybe (6)
I believe the answer is:
muesli
'breakfast maybe' is the definition.
'muesli' can be an answer for 'breakfast' (common breakfast food). I'm not certain of the 'maybe' bit.
'use lime but not all of it to make healthy' is the wordplay.
I cannot really understand how this works, but
an anagram of 'use' is 'ues' which is located in the answer.
The remaining letters 'mli' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for muesli that I've seen before include "Breakfast mush" , "Mixture of untoasted dry cereals and fruits" , "Breakfast food of cereals, fruits, nuts etc" , "Mule is fed with breakfast compound" , "Oat-based breakfast cereal" .)
