[header] How to eat pizza for breakfast [title] Grill leftover pizza on a waffle iron. [step] Instead of just eating cold, leftover pizza, heat it up on your waffle iron. Take one large piece of leftover pizza and fold it in half lengthwise, so the toppings are contained. 
If any toppings or cheese are oozing out, use a knife to trim them away. Put the pizza on a hot waffle iron and cook it until the outside of the pizza is crisp.
