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.
