Cases of dough with savoury fillings (7)
I believe the answer is:
ravioli
'cases of dough with savoury fillings' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for ravioli that I've seen before include "(Meat, cheese, etc filled) pasta cases" , "you might have at La Scala?" , "Italian dish (1)" , "Filled pasta squares" , "Small square pasta cases containing savoury filling" .)
