Vince: Yah, they are what we a call "mangiacake"
Reasons for an Italian-Canadian to call someone a mangiacake:
If you use butter to cook, versus extra virgin olive oil, then you are a mangiacake.
If your pasta sauce is from a jar branded as Ragu, Prego, etc, then you are a mangiacake.
If you pronounce Bruschetta as "broo-sh-edda", you are a mangiacake.
