These days pizza can arrive by car, delivery bot and even drone. Now you can also get a piping hot pie from a vending machine.

What's happening: PizzaForno, a Toronto-based company, is rolling out its automated pizza vending machines across North America, including in Michigan and other U.S. locations. For $10 to $13, they can serve up a hot, 12-inch pizza in under three minutes.

How it works: The pizza is fresh, not frozen, and made by humans but served by a robot.

I selected a $12 pepperoni pizza the other night from a PizzaForno machine in Ann Arbor, near the University of Michigan campus.

This isn't an entirely new idea. As Erica Pandey noted when she enjoyed server-less dumplings in New York recently, such efforts are reminiscent of the automats of the past, where food appeared in coin-operated kiosks.

The bottom line: Post-pandemic labor shortages could lead to more automated food service in the future.
