Press the 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 avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the tofu cubes to the skillet and sear until golden brown and crispy on all sides, approximately 8-10 minutes.
Toss in the broccoli florets, sliced red bell pepper, and edamame, stir-frying for 5 minutes until the vegetables are tender-crisp.
Pour the prepared sauce over the tofu and vegetables, tossing well to ensure every piece is coated.
Remove from heat, drizzle with toasted sesame oil, and garnish with sesame seeds, sea salt, and black pepper.
