Greatest fried egg bits (7)
I believe the answer is:
biggest
'greatest' is the definition.
('big' can be similar in meaning to 'great')
'fried egg bits' is the wordplay.
'fried' indicates an anagram.
'egg'+'bits'='eggbits'
'eggbits' is an anagram of 'BIGGEST'.
(Other definitions for biggest that I've seen before include "Superlatively large" , "Largest" , "Extremely great" , "Greatest in size" .)
