ravioli

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

'filled envelopes' is the definition.
(pasta envelopes)

'artist on fiddle endlessly' is the wordplay.
'artist on' becomes 'ra' (I can't justify this - if you can you should give a lot more credence to this answer).
'fiddle' becomes 'violin' (synonyms).
'endlessly' means to remove the last letter.
'violin' with its final letter removed is 'violi'.
'ra'+'violi'='RAVIOLI'

Can you help me to learn more?
