Combine the sauce ingredients in a bowl and set aside.
Bring a pot of water to a boil. Add the soba noodles and cook according to the package instructions. Drain and rinse with cold water.*
Heat the sesame oil in a pan over medium heat. Add the garlic, ginger and whites of the green onions. Cook for 30-60 seconds.
Add the shallot and mushrooms and stir to combine. Cook for 3-5 minutes or until the mushrooms have browned. Add the kale and toss until it begins to wilt.
Pour the sauce into the pan and add the noodles. Continue to toss until the sauce is absorbed and the noodles are heated through.
Serve warm with sesame seeds and the remaining green onions.
*If the noodles start to stick while you are prepping everything else, just give them another rinse of cold water.
**This makes 2 large entree portions or 4 smaller side portions.
