Wrap the extra-firm tofu in a clean kitchen towel and press for 15 minutes to remove excess moisture.
Cut the pressed tofu into 1-inch cubes and season evenly with sea salt and black pepper.
In a small bowl, whisk together the tamari, rice vinegar, sriracha, minced ginger, and minced garlic to create the glaze.
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 for 8-10 minutes, turning occasionally until all sides are golden brown and crispy.
Toss in the broccoli florets, red bell pepper, and shelled edamame, sautéing for 5 minutes until the vegetables are tender-crisp.
Pour the ginger-garlic glaze over the tofu and vegetables, stirring constantly for 1-2 minutes until the sauce thickens and coats everything.
Transfer the stir-fry to a bowl and serve immediately while hot.
