Bring a pot of water to a boil and cook the soba noodles according to package instructions, then drain and set aside.
In a small mixing bowl, whisk together the tahini, tamari, chili oil, ground Sichuan peppercorns, and rice vinegar until a smooth sauce forms.
Heat a large non-stick skillet over medium-high heat and add the ground turkey, seasoning it with sea salt and black pepper.
Sauté the turkey for 6-8 minutes, breaking it into small crumbles with a spatula until it is browned and cooked through.
Stir in the minced garlic, ginger, and chopped baby bok choy, cooking for another 2 minutes until the greens are tender and fragrant.
Add the cooked soba noodles to the skillet and pour the prepared Sichuan sauce over the top.
Toss everything together for 1-2 minutes until the noodles and turkey are thoroughly coated and the dish is steaming hot.
Transfer to a bowl and garnish with freshly sliced green onions before serving.
