Bring a pot of water to a boil. While you wait for that to boil, prep the veggies. Add the soba noodles to the water. Cook for 3-5 minutes, or until tender. Drain and rinse with cold water.*
Meanwhile, heat the sesame oil in a skillet over medium heat. Add the garlic, mushrooms, whites of the bok choy, whites of the green onions, white pepper and red pepper flakes. Cook down until the mushrooms have released their liquid and it has cooked off (approx. 5 minutes). Add 2 tablespoons of teriyaki sauce and cook for 1 more minute.
Add the soba noodles, greens of the bok choy and the rest of the teriyaki sauce.** Toss until everything is coated and heated through. Remove from the heat and serve with the remaining green onion and sesame seeds.
*If they start sticking together at any point, just rinse with more water.
**I like to add a couple tablespoons of teriyaki sauce at a time until I find the sweet spot. You may need more or less than 1/3 cup depending on the brand you use.
