Squabble, ban duke spoiling fried dish (6,3,6)
I believe the answer is:
bubble and squeak
'fried dish' is the definition.
'bubble and squeak' can be an answer for 'dish' (bubble and squeak is a kind of dish). I'm unsure of the 'fried' bit.
'squabble ban duke spoiling' is the wordplay.
'spoiling' indicates anagramming the letters.
'squabble'+'ban'+'duke'='squabblebanduke'
'squabblebanduke' is an anagram of 'BUBBLE-AND-SQUEAK'.
Can you help me to learn more?
(Other definitions for bubble and squeak that I've seen before include "Dish of leftovers" , "food" , "breakfast?" , "course" .)
