Drain the extra firm tofu and press it between paper towels for 10 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the tamari, grated fresh ginger, minced garlic, and rice vinegar to create the stir-fry sauce.
Heat the toasted sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu cubes to the skillet in a single layer and sear for 5-7 minutes, turning occasionally until all sides are golden brown and crispy.
Toss in the broccoli florets, sliced red bell pepper, and shelled edamame, sautéing for 4-5 minutes until the vegetables are tender-bright.
Pour the prepared sauce over the tofu and vegetables, stirring constantly for 1-2 minutes until the glaze thickens and coats everything evenly.
Season with sea salt and black pepper, then garnish with sesame seeds before serving hot.
