First, Pizza was invented by the Chinese but it was different, just telling you...
But why would Sokka make it, he eats nasty food..
I would think of Toph or Aang could of create it..
Well, guess it didn't become popular in China. I heard the German sausage was also invented in China!
Well, just to let you guys know, in Chinese it's either called "PISSA" or "Italian thick cookie". Trust me, I know it.
In Cantonese most people simply call it "pizza", or rather, "pissa", but in Mandarin they like to make things complicated and call it "Italian thick cookie" or "Yi da li bo bing"
