Press the firm tofu between paper towels for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Heat the toasted sesame oil in a large non-stick skillet over medium-high heat.
Add the tofu cubes to the skillet and sear until golden brown and crispy on all sides, about 8-10 minutes.
Toss in the broccoli florets, sliced red bell pepper, and edamame, sautéing for 5 minutes until the vegetables are tender-crisp.
Stir in the minced garlic and ginger, cooking for 1 minute until fragrant.
Whisk together the tamari and rice vinegar in a small bowl, then pour over the stir-fry.
Season with sea salt and black pepper, tossing everything to coat in the glaze.
Serve immediately, garnished with hemp seeds and sesame seeds for extra protein and texture.
