I am a big fan of eating at pizzeria chains, how about you?
I love pizza, so yes!  What is your favorite pizza?
I like pretty much any pizza, but I do like to have a mixture of meats and vegetables on mine -- chicken or hamburger are my favorite meats!
Yeah, I like chicken on mine as well.  Who invented the pizza?
Well, I don't think we can identify the person, but the first use of the word 'pizza' is from the 10th century in southern Italy. So it's an old food.
Wow!  I didn't know pizza was that old!  What was on the original pizza?
Nobody knows for sure, but traditionally it was just bread, cheese and tomato sauce.
Yummy!  Is pizza popular all over the world?
