Press the firm tofu between paper towels for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the tamari, rice vinegar, grated fresh ginger, and minced garlic 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 and sear until all sides are golden brown and crispy.
Toss in the broccoli florets, sliced red bell pepper, and shelled edamame, sautéing for 5-7 minutes until the vegetables are tender-crisp.
Pour the 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.
