First couple of breakfast eggs served up well done (5)
I believe the answer is:
bravo
'well done' is the definition.
(I've seen this before)
'first couple of breakfast eggs served up' is the wordplay.
'first' is a charade indicator (letters next to each other).
'couple of breakfast' becomes 'br' (I can't justify this - if you can you should give a lot more credence to this answer).
'eggs' becomes 'ova' (term for egg cells).
'served up' is a reversal indicator.
'ova' in reverse letter order is 'avo'.
'br' put next to 'avo' is 'BRAVO'.
(Other definitions for bravo that I've seen before include "Expression of approval" , "Exclamation of approval" , "West Indian cricket captain" , "Good job!: international radio code word" , "A cry meaning well done" .)
