Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Heat a large non-stick skillet over medium-high heat with half of the toasted sesame oil.
Add tofu cubes to the skillet and sear until golden brown on all sides, approximately 8-10 minutes.
Remove tofu from the pan and add the remaining oil, broccoli, red bell pepper, and edamame.
Sauté the vegetables for 5 minutes until they are tender-crisp.
In a small bowl, whisk together the tamari, rice vinegar, fresh ginger, garlic, and sriracha.
Return the tofu to the pan, pour the sauce over the mixture, and toss to coat for 2 minutes.
Sprinkle with sea salt, black pepper, and sesame seeds before serving.
