Bread covered in cheese with bits of meat on it is a really good combo : p
As for a favorite pizza, I have no idea : p Probly the stuffed kind, with all the cheese and toppings in it, Im sure : p
And pffft pineapple on pizza is great, I dont get why people are against it.
Ive never had sardines though, but I imagine Id be grossed out by it, haha.
