Prize dining experience containing starter of duck (5)
I believe the answer is:
medal
'prize' is the definition.
(I know that prize can be written as medal)
'dining experience containing starter of duck' is the wordplay.
'dining experience' becomes 'meal' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'containing' means one lot of letters goes inside another.
'starter of' indicates taking the first letters.
The initial letter of 'duck' is 'd'.
'meal' placed around 'd' is 'MEDAL'.
Can you help me to learn more?
(Other definitions for medal that I've seen before include "Gong (sl.)" , "Award for merit" , "Lamed (anag)" , "Lamed for a gong" , "George Cross, for instance" .)
