Italian food is so delicious!
I completely agree! It's one of my favorite kinds of food
It is amazing that Italian food is so good but the dishes, generally, only consists of two to four main ingredients.
I hadn't thought of that before, it mostly is simple. Yet the flavors are astounding
There has been a lot of practice since the cuisine goes back to the 4th century.
That is a long time. Has it always been fairly the same?
Well, there are differences due to Italy's regional diversity, especially between the North and South of the peninsula.  
I always thought of Italian as just being Italian. I suppose it's the same as cooking in the U.S.
True.  Plus the major components of the cuisine are pretty much the same with pasta, vegetables olive oil and fish.  but the flavors must differ regionally, just like the US, I suppose.
That's interesting. What's another interesting fact about Italian cuisine?
