N.Italy: I'm quarantined [well, it's lockdown, really] with two Italians, one is my wife (other is son): I'm not allowed even remotely near the kitchen. Every mealtime has become a stereotypically-italian ultra-marathon. 2.4kg heavier since. Yes, i am trying to keep fit but going from 30-200km daily bicycle rides (eas 28km commute and back for work) to balconia+pasta+pasta sure takes it toll.
As an Italian, I agree with your wife: my countrymen can be downright racist when it comes to food. Often they struggle to accept even other Italian food that is not from their own city. Then again, that's how Italian cuisine managed to survive the industrial revolution whereas others didn't make it.
In my case it is my significant other which had trouble adapting to Italian food. I took over the kitchen anyway :-), and I'm learning how to cook Turkish food, which is as wonderful as the Italian food.
