We can all agree that food looks pretty different from country to country. You most likely won't find arepas in Thailand or breakfast waffles in China. But there are foods that are so good that many countries have adopted their own version. And, of course, pizza is one of those foods.
Many of us believe Italy to be the originator of pizza, with the U.S. taking its own momentus interpretation on it (like the world's largest pizza box that served up to 70 people), but pizza may have been around as long as flatbread has -- which is a very long time ago.
Some people think that pizzas were adapted from the Greek's plankuntos. Others think Marco Polo brought the idea back from China when he saw scallion pancakes. We don't really care where it came from, we're just happy it's here. And we're grateful for every iteration it comes in.
