My favourite pizza would have to be Vegetarian as I never used to eat meat so that has just kind of stuck. I do eat meat though now as my second favourite pizza is Meat Lovers with barbeque sauce. I don't like tomato sauce >.>

Oh and as for bases I like the standard base. I liked this base Pizza Hut had for awhile it was like herb and garlic or something. It doesn't exist anymore though. The only pizza I really like thin crust is Pepporoni it's just the best that way.
