Cereal to eat with cooked meat dish (5)
I believe the answer is:
brawn
'cooked meat dish' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'cereal to eat with' is the wordplay.
'cereal' becomes 'bran' (type of cereal).
'to eat' is an insertion indicator.
'with' becomes 'w' (abbreviation).
'bran' placed around 'w' is 'BRAWN'.
Can you help me to learn more?
(Other definitions for brawn that I've seen before include "Pressed cooked meat; strength" , "Muscle (as opposed to brain)" , "Muscularity" , "Beefiness" , "Strength; a jellied loaf" .)
