Italian food — the way to circumvent depression (7)
I believe the answer is:
lasagne
'italian food' is the definition.
(type of pasta)
'way to circumvent depression' is the wordplay.
'way' becomes 'lane' (lane is a kind of way).
'to circumvent' indicates putting letters inside.
'depression' becomes 'sag' (sag is a kind of depression).
'lane' going around 'sag' is 'LASAGNE'.
'the' acts as a link.
(Other definitions for lasagne that I've seen before include "Form of pasta" , "Tasty Italian dish with layers of mince in pasta" , "The Italian dish is a gas, Len" , "Flat sheets of pasta" , "Course" .)
