1. Reheat cold pizza face down in a pan. Slap your slice of pizza face down on a preheated skillet on medium-high heat. You can either use a cast-iron pan with a little oil or a nonstick pan. Cook until the cheese has melted and formed a slight crust, about five minutes. Flip your pizza and cook on the other side for a few more minutes for a delicious melted pie.
2. Add water to the bottom of a skillet. Turn your burner to medium-low heat. Cook your pizza, crust down, for about a minute or two and add two teaspoons of water to the bottom of the pan. Cover the skillet and cook for another few minutes until the cheese has melted for a perfectly crisp crust
3. Waffle-iron your leftover pizza. If you learn one thing from this post, it’s that you need to use a waffle iron more. Grab a slice of pizza and add extra toppings to the upper left hand corner. Take the bottom corner of the pie, and fold it up toward the toppings. Chop off the crust.
