Do I have an amazing technique for you! It will ensure that it’s as close to the original as possible.  First begin by heating up your empty cast iron skillet over high heat on the stove. While it is warming up microwave your slices of pizza for 1-2 minutes. You want the pizza to be about 70 percent warm. Carefully remove pizza slices from the microwave and immediately place them in the hot skillet. This will allow the bottom to get crispy. Leave it there for 1-2 minutes or until the bottom is crispy and the toppings are hot.  We have used this technique with every kind of pizza. Works like a charm every time.
