Adjusted sound of quiz with plenty of meat (5,5)
I believe the answer is:
mixed grill
'plenty of meat' is the definition.
'adjusted sound of quiz' is the wordplay.
'adjusted sound of' becomes 'mixed' (I can't justify this - if you can you should believe this answer much more).
'quiz' becomes 'grill' (subject to questioning).
'mixed'+'grill'='MIXED GRILL'
'with' is the link.
Can you help me to learn more?
(Other definitions for mixed grill that I've seen before include "Meal of assorted meats" , "Dish of meats and vegetables" , "Sausages, bacon, kidneys, tomatoes, mushrooms, etc" , "Dish of various meats and veg" .)
