Bring a pot of water to a boil and cook the soba noodles according to package directions, adding the baby bok choy for the last 60 seconds of boiling.
Drain the noodles and bok choy, then set them aside.
In a small bowl, whisk together the tahini, tamari, chili oil, ground Sichuan peppercorns, rice vinegar, and coconut aminos to create the sauce base.
Heat the avocado oil in a large skillet over medium-high heat.
Add the minced ginger and garlic to the skillet, sautéing for 30 seconds until fragrant.
Add the ground turkey to the skillet, seasoning with sea salt and black pepper, and cook until browned and fully cooked through.
Reduce the heat to low and add the cooked noodles, bok choy, and the prepared sauce to the skillet.
Toss all components together until the noodles are well-coated and the mixture is heated through.
Serve immediately in a bowl, garnished with the sliced green onions.
