Bring a medium pot of water to a boil and cook the soba noodles for 4-5 minutes until tender, then drain and set aside.
In a small mixing bowl, whisk together the tahini, tamari, chili oil, and toasted sesame oil until the sauce is smooth and emulsified.
Heat a large non-stick skillet over medium-high heat and add the ground pork, breaking it apart with a spatula.
Season the pork with sea salt and black pepper, cooking until browned and no longer pink.
Stir in the minced garlic and grated fresh ginger, sautéing for 60 seconds until the aromatics are fragrant.
Add the chopped baby bok choy to the skillet and cook for 2 minutes until the leaves are wilted and the stems are slightly tender.
Reduce the heat to low, add the cooked soba noodles and the prepared tahini sauce to the skillet.
Toss everything thoroughly for 1 minute to ensure the noodles and pork are evenly coated in the creamy sauce.
Divide into a bowl and garnish with freshly sliced scallions before serving.
