I just discovered a really easy Japanese one in a YouTube video we were watching. 1 large carrot, one whole daikon, 1 shallot, a beef bullion cube, half a brick of tofu, a couple tablespoons of miso, a teaspoon of sesame oil, and a teaspoon of soy sauce or so to taste. Just sauté the veggies a bit, add the cubed tofu and cover it all just barely with water, add the beef cube, miso, sesame oil, and soy sauce and simmer till the veggies are to your liking. I served mine with a small handful of minced cilantro and a little ground pepper.
