Cook squabbled with EU bank for recycled food (6,3,6)
I believe the answer is:
bubble and squeak
'recycled food' is the definition.
(meal made from leftover food)
'cook squabbled with eu bank' is the wordplay.
'cook' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'eu'+'bank'='eubank'
'squabbled' after 'eubank' is 'eubanksquabbled'.
'eubanksquabbled' with letters rearranged gives 'BUBBLE-AND-SQUEAK'.
'for' acts as a link.
(Other definitions for bubble and squeak that I've seen before include "food" , "Dish of leftovers" , "breakfast?" , "course" .)
