Pizza is my favorite food.  It is a traditional Italian dish that basically flatbread with toppings. 
Oh gosh I love pizza so much. Nothing like a nice margherita pizza in the afternoon with wine.
Yes I like Margherita pizza too.  That is made San Marzano tomatoes. 
Oh I did not know that! I love basil, i grow my own
The last half of the 20th century saw pizza become a worldwide accepted dish. Mostly due to Italian immigrants. 
That's so cool. Immigrants are important to the US, we need them because we would never have pizza.
Modern pizza was an invention of the city Naples.  
Hm interesting. So Chicago deep dish and those types originate from there? Or is it very Americanized
