Supplying food for virgin mixed with poison (12)

I believe the answer is:

provisioning

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

'supplying food' is the definition.
'provisioning' can be an answer for 'supplying' (provisioning is a kind of supplying). I'm not sure about the 'food' bit.

'virgin mixed with poison' is the wordplay.
'mixed with' indicates an anagram.
'virgin' mixed up with 'poison' gives 'PROVISIONING'.

'for' is the link.

Can you help me to learn more?
