Breakfast cereal and fruit mix (6)
I believe the answer is:
muesli
(Other definitions for muesli that I've seen before include "Breakfast cereal mix" , "Breakfast food of cereal, nuts, dried fruit etc with milk" , "Cereal made with oats and nuts" , "Breakfast dish with cereals, nuts, fruit etc" , "Breakfast food of cereals, fruits, nuts etc" .)
