Pot filled with starter of ratatouille, call for dinner (8)

I believe the answer is:

prandial

'for dinner' is the definition.

'pot filled with starter of ratatouille call' is the wordplay.
'pot' becomes 'pan' (I've seen this in other clues).
'filled with' indicates putting letters inside.
'starter of' suggests taking the first letters.
'call' becomes 'dial' (I've seen this in another clue).
The first letter of 'ratatouille' is 'r'.
'pan' going around 'r' is 'pran'.
'pran'+'dial'='PRANDIAL'

(Another definition for prandial that I've seen is " Relating to a meal".)

I've seen this clue in The Guardian.
