Choice cuisine ultimately containing few calories (5)
I believe the answer is:
elite
'choice' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for elite that I've seen before include "Superior group in society" , "A privileged or superior social group" , "Creme de la creme" , "Exclusive set" , "Group considered to have superior status" .)
