Angela's cooked an Italian dish (7)
I believe the answer is:
'an italian dish' is the definition.
(I've seen this before)
'angela's cooked' is the wordplay.
'cooked' indicates an anagram (letters cooked into a new form).
'angelas' anagrammed gives 'LASAGNE'.
(Other definitions for lasagne that I've seen before include "Fool ran as angel (anag) - pasta dish" , "Form of pasta" , "Course" , "Wide flat strips of pasta" , "continental dish" .)
