Here's my idea for "five-kingdom stew".
It's red bean chili with mushrooms and kelp, served with some sour cream on top. Then you have "all" five kingdoms in there:
* red beans are the representatives of the plants.
* mushrooms are representatives of the fungi
* kelp is the representative of the protists. If someone has an idea for a more delicious protist, let me know.
* The cream comes from animals (I don't eat meat, but I know some people do)
* The sourness of the cream is from bacteria.
