Limes and core of fruit in a salad that's eaten for breakfast (6)
I believe the answer is:
muesli
'eaten for breakfast' is the definition.
'muesli' can be an answer for 'breakfast' (common breakfast food). I am not certain of the 'eaten for' bit.
'limes and core of fruit in a salad' is the wordplay.
'and' says to put letters next to each other.
'core of' means to look at the middle letters.
'in a salad' indicates anagramming the letters (salad can mean a mixture).
The central letter of 'fruit' is 'u'.
'limes' after 'u' is 'ulimes'.
'ulimes' with letters rearranged gives 'MUESLI'.
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for muesli that I've seen before include "Breakfast dish of cereal, nuts and fruit (6)" , "Breakfast mix of oats, nuts, fruit etc" , "Breakfast dish with cereals, nuts, fruit etc" , "Cereal made with oats and nuts" , "Mixture of untoasted dry cereals and fruits" .)
