Although sicilian pizza is often used to refer to a pie with a thick, rectangular, sheet pan-sized crust, there can be a little more to it than just its shape and size. In sicily, a generous, almost focaccia-like crust is commonly topped with an abundance of strong cheese and sauce (in that order), along with onions, anchovies, and herbs. Our version here is a riff on these sicilian toppings, layered onto a golden, crispy bottomed, soft and chewy crust.
