Bring a medium pot of water to a boil and cook the soba noodles for 4-5 minutes until tender, then drain and rinse with cold water.
In a large skillet over medium-high heat, add the toasted sesame oil and the ground pork.
Season the pork with sea salt and black pepper, breaking it apart with a spatula until browned and cooked through.
Stir in the minced garlic and grated ginger, cooking for 1 minute until the aromatics are fragrant.
Add the chopped baby bok choy to the skillet and sauté for 2-3 minutes until the leaves are wilted and the stems are tender-crisp.
In a small bowl, whisk together the tamari, chili oil, rice vinegar, and coconut aminos to create the sauce.
Add the cooked soba noodles and the sauce to the skillet, tossing everything together for 1-2 minutes until well-coated and heated through.
Garnish with sliced green onions and serve immediately while hot.
