Bring a medium pot of water to a boil and cook the soba noodles for 4-5 minutes until tender, then drain and rinse with cold water to prevent sticking.
Heat a large skillet over medium-high heat and add the ground turkey, breaking it into small crumbles with a wooden spoon.
Season the turkey with sea salt and black pepper, cooking until browned and fully cooked through.
Add the sliced red bell peppers and chopped bok choy to the skillet, sautéing for 3 minutes until the vegetables are vibrant and tender-crisp.
Stir in the minced garlic and grated ginger, cooking for 60 seconds until the aroma is released.
In a small bowl, whisk together the tamari and toasted sesame oil, then pour the mixture over the turkey and vegetables.
Add the cooked soba noodles to the skillet and toss thoroughly to ensure the savory sauce is evenly distributed.
Transfer to a bowl and garnish with freshly sliced green onions before serving.
