Bring a pot of water to a boil and cook the soba noodles according to package directions, adding the chopped baby bok choy during the last minute of cooking to blanch.
Drain the noodles and bok choy thoroughly, then set aside.
In a large skillet or wok, heat the avocado oil over medium-high heat.
Add the ground turkey and sea salt, breaking the meat up with a spatula until browned and cooked through.
Stir in the minced garlic and grated ginger, cooking for 1 minute until fragrant.
In a small bowl, whisk together the tahini, coconut aminos, chili oil, and ground Sichuan peppercorns to create the sauce.
Add the drained noodles and bok choy to the skillet with the turkey.
Pour the sauce over the mixture and toss everything together until well-coated and heated through.
Serve immediately, garnished with sliced green onions.
