Pizza is looking more affordable.
Granted, I make pizzas in bulk, meaning at least a dozen pies if I'm going through the effort, so my costs reflect quantity preps. Nevertheless, any way you slice it (pun intended) pizza is cheap to make.
Ingredients to make my 14"-16" pizza pies at home:
Crust - 20¢
Tomato sauce - 25¢
Good quality mozzarella cheese (6 oz) - $1.00
Other toppings, if desired $1.00
That comes to $1.50 for a basic cheese pizza. Up to $3.50 if you load on the cheese plus another topping. Even overestimating the cost of running the oven at 50¢, it's between $2 - $4.
Price out the door for an XL (20") cheese pizza at my local pizzeria? $34.95.
Domino's is $21.89 for a 16" plain cheese pizza.
Topping ingredients don't spoil easily, either, so pizzerias don't deal with the costly waste other food places suffer.
And people wonder why there are so many pizza joints around.
The best buy on pizza has to be Costco's take and bake or food court. $1.99/slice or $9.95 for an 18" pie at the food court, not sure of the price on their take-and-bake but it's probably in the same range. As I recall, their pizza is quite tasty.
