Bring a medium pot of water to a boil and cook the soba noodles according to the package instructions until tender, then drain and set aside.
While the noodles cook, heat a large non-stick skillet over medium-high heat and add the ground turkey, breaking it apart with a spatula.
Season the turkey with sea salt, black pepper, minced garlic, and grated fresh ginger, cooking until the meat is browned and cooked through.
Add the chopped baby bok choy to the skillet and sauté for 2 minutes until the leaves are wilted and the stems are slightly tender.
In a small bowl, whisk together the toasted sesame oil, tamari, chili garlic sauce, and tahini until smooth.
Add the cooked soba noodles and the sauce mixture to the skillet, tossing everything together for 1 minute to coat thoroughly and heat through.
Divide the noodles into a bowl and garnish with sliced green onions before serving.
