Finger sandwiches reverted to whatever's available (3,4)
I believe the answer is:
pot-luck
'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?
I've seen this clue in The Telegraph.
