Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Heat a non-stick skillet over medium-high heat and add the toasted sesame oil.
Add tofu cubes to the pan and sear until golden brown on all sides, about 8-10 minutes.
Toss in the broccoli florets and shelled edamame, sautéing for 5 minutes until the broccoli is tender-crisp.
In a small bowl, whisk together the tamari, rice vinegar, garlic powder, and ground ginger.
Pour the sauce over the tofu and vegetables, stirring constantly for 1-2 minutes until well coated.
Garnish with sliced green onions and toasted sesame seeds before serving.
