Bring a pot of water to a boil and cook the soba noodles according to package directions, then drain and set aside.
Heat a large skillet over medium-high heat and add the ground pork, breaking it into small crumbles with a spatula.
Season the pork with sea salt and black pepper, cooking until it is golden brown and no longer pink.
Stir in the minced garlic, grated ginger, and the chopped white parts of the green onions, sautéing for 1 minute until fragrant.
Add the chopped bok choy to the skillet and cook for 2 minutes until the leaves are wilted and the stems are tender-crisp.
In a small bowl, whisk together the tamari, toasted sesame oil, and chili garlic sauce to create the dressing.
Add the cooked soba noodles and the sauce to the skillet, tossing everything together to coat the noodles and pork evenly.
Garnish the dish with the sliced green onion tops and serve immediately while hot.
