'revolutionary bees' is the definition.
Although both the answer and definition are plural nouns, I can't see how they can define each other.

'ruined tout's fast food' is the wordplay.
'ruined tout' becomes 'cheese' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'fast food' becomes 'burgers' (burgers are a type of fast food).
'cheese'+'burgers'='CHEESEBURGERS'
