Free gig, roughly accommodating 500 for breakfast (5,3)
I believe the answer is:
fried egg
'breakfast' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'free gig roughly accommodating 500' is the wordplay.
'roughly' indicates anagramming the letters.
'accommodating' is an insertion indicator.
'500' becomes 'D' (Roman numeral for 500).
'free'+'gig'='freegig'
'freegig' is an anagram of 'frieegg'.
'frieegg' enclosing 'd' is 'FRIED EGG'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for fried egg that I've seen before include "Breakfast favourite" , "Feature of an English breakfast" , "Accompaniment to bacon" , "Yellow and white cooked item" .)
