Second dish, no starter (6)
I believe the answer is:
latter
'second' is the definition.
(latter can mean the second of two mentioned things)
'dish no starter' is the wordplay.
'dish' becomes 'platter' (platter is a kind of dish).
'no starter' means to remove the first letter.
'platter' with its initial letter taken away is 'LATTER'.
(Other definitions for latter that I've seen before include "That follows" , "Last-mentioned" , "The one just mentioned" , "Second-mentioned; recent" , "Concluding" .)
