Food and very quiet beer outside (5)
I believe the answer is:
apple
'food' is the definition.
(apple is a kind of food)
'very quiet beer outside' is the wordplay.
'very quiet' becomes 'pp'.
'beer' becomes 'ale' (I've seen this before).
'outside' indicates putting letters inside.
'pp' put within 'ale' is 'APPLE'.
'and' is the link.
(Other definitions for apple that I've seen before include "Dressing; Irish county" , "Granny Smith, for one" , "Pomaceous fruit" , "Jonathan perhaps" , "Fruit that's Big in the US" .)
