Angela’s cooking an Italian dish (7)
I believe the answer is:
lasagne
'italian dish' is the definition.
(I've seen this before)
'angela's cooking' is the wordplay.
'cooking' indicates an anagram (letters cooked up into a new form).
'angelas' anagrammed gives 'LASAGNE'.
'an' is the link.
(Other definitions for lasagne that I've seen before include "The Italian dish is a gas, Len" , "Flat sheets of pasta" , "Eat this as angel" , "Layered pasta dish" , "Type of pasta" .)
