Cheese-coated fish starter, simply put (7)

'fish starter simply put' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'cheese-coated' is the wordplay.
I cannot really understand how this works, but
'cheese' could be 'brie' (Brie is an example) and 'brie' is found in the answer.
The remaining letters 'inf' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?
