Excellent meal, but requiring no repetition (5)
I believe the answer is:
super
'excellent' is the definition.
(I've seen this in other clues)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for super that I've seen before include "of high quality" , "Gushily great, excellent" , "Informally excellent, terrific" , "Prefix meaning above or informally great" , "Outstanding" .)
