What? Pizza is simple dough and cut veggies, maybe meat stripes and some grated cheese. If you think this is something that resembles a dish where you can taste if the maker is a good cook I really have a different view on food compared to you.

Freezing ingredients doesn't really make them taste super different on a pizza to me. Sure if you buy a cardboard cheap frozen pizza there is not much dough and toppings, but if you take the one that comes close to what you would pay in a restaurant it's not much different in my view.

I also think comparing the quality of cooking of Italy with France is unfair. Italy seems to have a way more basic cooking style.
