Not everybody has such... low effort palate so to say. Its not easy to have it once one tasted some properly well made food.

Don't do to France or Italy is my recommendation in all honesty, ignorance is a bliss.

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.
