Serious Eats — specifically J. Kenji López-Alt — has gone on a real waffling bender.

Take a look at the results (above, clockwise from upper left):

Stuffing: The waffle iron does what it does so well — maximizing those crispy bits. Oh, and making everything look sort of like a waffle.
Leftover French fries: I am not personally acquainted with the concept of leftover French fries, but if that fate were to befall someone this looks like it would be an excellent next step.
Falafel: An entire falafel sandwich goes into the waffle iron and comes out snack-ready.
Leftover pizza: The waffle iron makes an excellent alternative to eating leftover pizza cold from the box. In front of the refrigerator. For breakfast. Which is something I've heard that people do.
