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, grated fresh ginger, and minced garlic to create the stir-fry sauce.
Heat the 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 golden and crispy on all sides.
Add the broccoli florets and shelled edamame to the skillet, sautéing for 4-5 minutes until the vegetables are tender-crisp.
Pour the prepared ginger-tamari sauce over the tofu and vegetables, stirring constantly to coat everything evenly.
Sprinkle the nutritional yeast, sea salt, and black pepper over the mixture and stir for 1 minute as the sauce thickens.
Serve the tofu stir-fry over a bed of warm cooked quinoa and garnish with sesame seeds before serving.
