Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Whisk together tamari, rice vinegar, minced ginger, and minced garlic in a small bowl to create the sauce.
Heat sesame oil in a large non-stick skillet over medium-high heat.
Add tofu cubes to the skillet and sear until golden and crispy on all sides, approximately 8-10 minutes.
Add the broccoli, bell pepper, and edamame to the skillet, sautéing for 5 minutes until the vegetables are tender-crisp.
Pour the prepared sauce over the tofu and vegetable mixture, tossing well to coat until the sauce thickens slightly.
Season with sea salt and black pepper, then garnish with sesame seeds before serving hot.
