Structural variations of pizza, etc.

In our quest for truth, I googled pizza and found some good stuff. One idea was something I was already struggling with: what are the "other" things that are often sold in a pizza store (from remnant dough).

http://en.wikipedia.org/wiki/Pizza
Wikipedia calls this Structural Variations, to wit:

Stromboli
Calzone
Garlic Knots
I add: sausage rolls.

Also: Ethnic Variations: Greek pizza, Lahmacun , Manakish ,Mexican pizza,Pissaladière , Sardenara , Sicilian pizza

Also: Miscellaneous Variations: Tomato pie, Pizza bagel,Grilled pizza, Deep-fried pizza, Garlic fingers, Hawaiian pizza

Also: In the 20th century and onward, pizza has become an international food and the toppings may vary considerably in accordance with local tastes..diverse choice of ingredients, such as anchovies, egg, pineapple, banana, coconut, sauerkraut, eggplant, kimchi, lamb, couscous, chicken, fish, pierogies, french fries, shellfish, meats prepared in styles such as Moroccan lamb, shawarma or chicken tikka masala, and non-traditional spices such as curry, cilantro, cumin, and Thai sweet chili.

Now, RFers, we know as much as Wikipedia. What to you want to add?
