Why even make pizza? What is it really? Bread, cheese, toppings, and tomato sauce. I can knock that down to $0.25 or less per pizza.

Take a slice of bread, spread with tomato sauce, top with cheese and toppings, then broil until toppings melt. Want a calzone? Add a second piece of bread on top of the end, broil until toasted.

Boom. Pizza.
