Bring a small pot of water to a boil and cook the soba noodles according to package directions, then drain and set aside.
In a large skillet or wok, heat the toasted sesame oil over medium-high heat and add the ground pork, breaking it apart until fully browned.
Stir in the minced garlic, grated ginger, sea salt, and black pepper, cooking for one minute until the aromatics are fragrant.
Pour in the chicken bone broth, tamari, and sriracha, bringing the mixture to a gentle simmer to meld the flavors.
Add the chopped bok choy and shredded carrots to the broth, cooking for 2 to 3 minutes until the vegetables are tender yet crisp.
Divide the cooked noodles into a bowl, ladle the spicy pork and vegetable broth over the top, and garnish with sliced green onions.
