1. Prep your veggies and set them aside.
2. Combine all sauce ingredients in a small bowl and whisk until mixed.
3. Fill a large bowl with hot tap water and soak the noodles. Or, simply use fresh udon noodles directly from the package.
4. In a large frying pan or wok, add avocado oil and heat the pan to medium-high. Once hot, add carrots or hearty veggies of choice (we used red cabbage, zucchini, and bell peppers) for a minute or so and stir, followed by the onions for another thirty seconds or more. Stir all the veggies until tender.
5. Drain noodles or take them out of the package. If soaked, stir and cook in the pan for thirty seconds or more, until excess water evaporates.
6. Add sauce and cook for another thirty seconds, stirring the mixture so everything becomes well combined. Add spinach or any tender greens last, until wilted.
7. Serve into a bowl or plate, garnish and enjoy!
