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 large skillet over medium-high heat, add the ground turkey, minced ginger, minced garlic, sea salt, and ground Sichuan peppercorns.
Cook the turkey, breaking it into small crumbles with a spatula, until it is browned and cooked through.
Add the chopped 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 tamari, rice vinegar, sesame oil, and chili oil to create the sauce.
Add the cooked soba noodles to the skillet with the turkey and vegetables, then pour the sauce over the mixture.
Toss everything together for 1 minute to ensure the noodles are evenly coated and heated through.
Transfer to a bowl and garnish with sliced green onions before serving.
