You can also put other stuff with it as in the photo (click to enlarge), for
example red bell pepper, broccoli, potatoes, carrots, and chicken as shown
(this photos is from back in the days when you could still buy edible chicken
in the supermarket... nowadays, it's pumped full of foul-smelling liquid
that not only tastes bad and is probably toxic, but also makes it impossible
to sautée the chicken, because the liquid quickly fills the pan and the
chicken comes out boiled and tough). (Update: in the late 2000s, organic
chicken without additives is showing up in supermarkets.)
