ravioli

I'm a little stuck... Click here to teach me more about this clue!

'pasta dish' is the definition.
(I've seen this before)

'royal with a musical instrument not finishing' is the wordplay.
'royal with' becomes 'ra' (I can't explain this - if you can you should give a lot more credence to this answer).
'a musical instrument' becomes 'violin' (violin is a kind of musical instrument).
'not finishing' means to remove the last letter.
'violin' with its last letter removed is 'violi'.
'ra'+'violi'='RAVIOLI'

Can you help me to learn more?
