Bring a pot of water to a boil and cook the soba noodles according to package directions, adding the edamame during the last 2 minutes of cooking.
Drain the noodles and edamame, then rinse under cold water to stop the cooking process and set aside.
Pat the salmon fillet dry with a paper towel and season both sides with sea salt and black pepper.
Heat the toasted sesame oil in a non-stick skillet over medium-high heat.
Place the salmon in the skillet skin-side down and sear for 4-5 minutes until the skin is golden and crispy.
Flip the salmon and cook for another 3-4 minutes until cooked through, then remove from the pan and let rest.
In the same skillet, add the minced garlic, grated ginger, and chopped baby bok choy, sautéing for 2 minutes until the greens are wilted but the stems remain crisp.
Whisk together the tamari and lemon juice in a small bowl, then add it to the skillet along with the cooked noodles and edamame.
Toss everything together over low heat for 1 minute until well coated and warmed through.
Plate the zesty noodle mixture and top with the pan-seared salmon fillet.
