This guy knows it.
Pineapple on Pizza is the weirdest thing ever invented. This is coming from someone who has played a fair share of hentai
Too much pizza talk in the Dev Stream thread. 
As doner is popular in Germany and kebab shops often offer pizza, too, you can get doner pizza over here.
I ate a pizza like that in in Italy, also had a bit of meatballs like in the first pic. Was amazing
eisprinzessin: Shaworma/ Kebap in all shapes and sizes had become the most popular food here over the last decade
Invented by a Canadian. Most popular in Australia.
And I would recommend a slightly different variant of this:
Take peaches instead of pineapple, tuna instead of ham. Some onions…perfect. 
Tuna I can understand somehow, just not bacon
Tuna pizza’s good too. 
Also salami, mozzeralla, spinach, veg - all different types of pizza.
Pineapples/Jalapenos depending on the mood
