Press the extra firm tofu 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 a large non-stick skillet over medium-high heat and add the toasted sesame oil.
Add the tofu cubes to the skillet and sear for 8-10 minutes, turning occasionally until all sides are golden brown and crispy.
Add the broccoli florets, sliced red bell pepper, and shelled edamame to the pan, sautéing for 5 minutes until the vegetables are tender-crisp.
Pour the prepared sauce over the tofu and vegetable mixture, stirring constantly for 1-2 minutes until the glaze thickens and coats the ingredients evenly.
Season the stir-fry with sea salt and black pepper, then garnish with sesame seeds before serving hot.
