Press the extra firm tofu for at least 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a medium bowl, toss the tofu cubes with nutritional yeast, sea salt, and black pepper until evenly coated.
Heat the avocado oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu to the skillet and sear for 8-10 minutes, turning occasionally, until all sides are golden and crispy.
Add the broccoli florets, sliced red bell pepper, and shelled edamame to the skillet, sautéing for 5 minutes until the vegetables are tender-crisp.
Stir in the minced ginger, minced garlic, tamari, and toasted sesame oil, cooking for an additional 2 minutes until the aromatics are fragrant.
Remove from heat and garnish with sliced green onions before serving.
