Dish in sink getting in the way (7)
I believe the answer is:
lasagne
'dish' is the definition.
(lasagne is a kind of dish)
'sink getting in the way' is the wordplay.
'sink' becomes 'sag' (sagging is a kind of sinking).
'getting in' is an insertion indicator.
'the way' becomes 'lane' (lane is a kind of way**).
'sag' placed within 'lane' is 'LASAGNE'.
'in' acts as a link.
(Other definitions for lasagne that I've seen before include "Italian cooking" , "Lea sang out for the pasta dish" , "The Italian dish is a gas, Len" , "Sheet pasta" , "Italian food" .)
