Foreign character lies about fare from Europe (6)
I believe the answer is:
muesli
'fare from europe' is the definition.
(food originally from Switzerland)
'foreign character lies about' is the wordplay.
'foreign character' becomes 'mu' (Greek letter).
'about' indicates an anagram.
'lies' is an anagram of 'esli'.
'mu'+'esli'='MUESLI'
(Other definitions for muesli that I've seen before include "Mixture of untoasted dry cereals and fruits" , "Breakfast food of cereals, fruits, nuts etc" , "Dish of dried fruit and cereals" , "eaten at breakfast" , "Cereal made with oats and nuts" .)
