This is the best way to reheat pizza that I have found. I copied it from the box of Moto Pizza which is the best pizza I have eaten.
Directions
- Preheat oven to 350 °F.
 - Rub a cookie sheet1 with butter.
 - Bake pizza on buttered surface for up to 8 minutes, or when the cheese is bubbling.
 
Can also use a skillet or baking stone. ↩︎
