Dish of rabbit set back in aisle (7)
I believe the answer is:
lasagne
'dish' is the definition.
(lasagne is a kind of dish)
'rabbit set back in aisle' is the wordplay.
'rabbit' becomes 'gas' (I've seen this before).
'set back' says the letters should be written in reverse.
'in' indicates putting letters inside.
'aisle' becomes 'lane' (I've seen this in another clue).
'gas' back-to-front is 'sag'.
'sag' put into 'lane' is 'LASAGNE'.
'of' is the link.
(Other definitions for lasagne that I've seen before include "Fool ran as angel (anag) - pasta dish" , "Pasta served in strips" , "Italian food" , "Course" , "Italian cooking" .)
