Bring a medium pot of water to a boil and cook the soba noodles according to package directions, then drain and set aside.
In a small bowl, whisk together the tahini, tamari, chili oil, toasted sesame oil, minced garlic, grated ginger, and water until the sauce is smooth and creamy.
Heat a large non-stick skillet over medium-high heat and add the ground turkey, seasoning with sea salt and black pepper.
Cook the turkey until browned and cooked through, breaking it into small crumbles with a wooden spoon.
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.
Add the cooked soba noodles and the prepared sauce to the skillet, tossing everything together for 1 minute until well-coated and heated through.
Transfer to a bowl and garnish with thinly sliced green onions before serving.
