Finger sandwiches reverted to whatever's available (3,4)

I believe the answer is:

pot-luck

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

'whatever's available' is the definition.
(random selection)

'finger sandwiches reverted to' is the wordplay.
'finger' becomes 'pluck' (I am not sure about this - if you are sure you should believe this answer much more).
'sandwiches' indicates putting letters inside (inserted letters are sandwiched in).
'reverted' is a reversal indicator.
'to' in reverse letter order is 'ot'.
'pluck' placed around 'ot' is 'POT-LUCK'.

Can you help me to learn more?
