Anchovie, Garlic and Onion are my favorite topping followed by HOT Italian sausage.
BTW, I take exception to the claim toppings make the Pizza. It is the sauce which determines if a Pizza is any good, followed by the dough used for the crust.
Traditional pizza crust brushed with garlic butter,
topped w/ sweet tangy honey BBQ sauce, 100% real cheese,
and deliciously seasoned BBQ'ed pulled pork.
