Boil water and cook soba noodles according to package directions, then drain and set aside.
In a small bowl, whisk together tahini, tamari, rice vinegar, chili oil, and sesame oil until smooth.
Heat a large skillet over medium-high heat and add the ground turkey, seasoning with sea salt and black pepper.
Brown the turkey for 5-6 minutes, breaking it into small crumbles until fully cooked.
Add the minced garlic, grated ginger, and chopped bok choy to the skillet, sautéing for 2-3 minutes until the greens are wilted.
Reduce heat to low, add the cooked noodles and sauce to the skillet, and toss everything together until evenly coated.
Serve in a bowl garnished with fresh green onions.
