Press the tofu between paper towels for 15 minutes to remove excess moisture, then cut into 1-inch cubes and season with sea salt and black pepper.
Cook the soba noodles in boiling water according to package directions, then drain and rinse with cold water to prevent sticking.
In a small bowl, whisk together the tamari, toasted sesame oil, minced ginger, and minced garlic to create the stir-fry sauce.
Heat avocado oil in a large skillet over medium-high heat and sear the tofu cubes for 3-4 minutes per side until golden brown and crispy.
Add the broccoli florets, red bell pepper, and edamame to the skillet, sautéing for 5 minutes until the vegetables are tender-crisp.
Toss in the cooked soba noodles and pour the sauce over the mixture, stirring constantly for 2 minutes until everything is well-coated and heated through, then garnish with sesame seeds.
