Beef Santa cooked for substantial meal (9)

I believe the answer is:

beanfeast

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

'substantial meal' is the definition.
'beanfeast' can be an answer for 'meal' (I've seen this before). I am not sure about the 'substantial' bit.

'beef santa cooked' is the wordplay.
'cooked' indicates an anagram (letters cooked into a new form).
'beef'+'santa'='beefsanta'
'beefsanta' with letters rearranged gives 'BEANFEAST'.

'for' is the link.

Can you help me to learn more?

(Other definitions for beanfeast that I've seen before include "Celebratory party" , "free meal" , "Party with lots of food and drink" .)

I've seen this clue in The Guardian.
