Meaty part said to be for a bad actor (3,4)

'meaty' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'part said to be for a bad actor' is the wordplay.
'part' becomes 'role' (eg a theatrical role).
'said to be' shows a homophone (sound like).
'for' means one lot of letters go next to another (I've seen this in other clues).
'a bad actor' becomes 'ham' (a ham is someone who overacts).
'role' is a homophone of 'roll'.
'roll' after 'ham' is 'HAM ROLL'.

Can you help me to learn more?
