From Candice Kumai's Kintsugi Wellness book: "Mom used to make this dish as a quick, filling meal for the family on busy days. Yakisoba is a simple, flavorful stir-fry noodle. Feel free to toss in your own leftover proteins and veggies to mix it up and make it your own!" —Candice Kumai
In a medium sauté pan warm the oil over medium heat. Add the onion and sauté for 5 minutes, stirring occasionally. Add the garlic and sauté for 2 minutes, until fragrant. Add the mushrooms and sauté for 2 to 3 minutes more, stirring well.
Add all the ingredients for the light yakisoba sauce to the pan and stir. Add the fresh yakisoba noodles and sauté for a few minutes, tossing to coat all the noodles with the sauce, and cook until the water evaporates.
Add the chopped kale and toss to slightly wilt and coat with the sauce. Divide the noodles among individual serving bowls and top with 1⁄2 teaspoon of sesame seeds per bowl.
