Bring a pot of water to a boil and cook the soba noodles according to package directions, then drain and set aside.
In a small bowl, whisk together the tamari, rice vinegar, and toasted sesame oil to create the stir-fry sauce.
Heat a large skillet or wok over medium-high heat and add the ground pork, seasoning it with sea salt and black pepper.
Cook the pork until browned and cooked through, breaking it into small crumbles with a spatula.
Add the grated ginger and minced garlic to the pork, sautéing for 1 minute until fragrant.
Toss in the shredded cabbage, carrots, and snap peas, stir-frying for 3-4 minutes until the vegetables are tender-crisp.
Add the cooked soba noodles and the prepared sauce to the skillet, tossing everything together for 2 minutes to coat and heat through.
Serve immediately, garnished with fresh sliced green onions.
