Warm olive oil in a soup pot over medium heat. Add the chopped onions, garlic and ginger and cook for 1-2 minutes.
Add the milk, broth, soy sauce, mirin and kabocha squash.. Cook for 5-7 minutes until the squash has cooked, but still has some bite. Add the shiitake, tofu and dumpling and simmer further until the dumplings are cooked through. (see instructions if using store bought dumplings).
Add the savoy cabbage leaves. They will wilt in the heat.
Lastly, take the miso in a ladle or large spoon add a little bit of the hot broth. Whisk until the miso has dissolved, stir it back into the soup. Mix well. Take the soup off the heat and set aside to serve.
To serve, ladle stew/soup into a bowl. Making sure each bowl has all the ingredients and equal share of dumplings. Drizzle with chili oil, garnish with toasted sesame seeds, green onions, pomegranate if available and serve!
