Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Press the extra-firm tofu between paper towels to remove excess moisture, then cut it into 1-inch uniform cubes.
In a large mixing bowl, combine the tofu cubes, broccoli florets, and halved Brussels sprouts.
Drizzle the mixture with avocado oil and season with sea salt, black pepper, and garlic powder, tossing thoroughly to ensure every piece is coated.
Spread the vegetables and tofu in a single layer on the prepared baking sheet, ensuring they aren't crowded so they roast rather than steam.
Roast in the oven for 20 minutes, then remove the tray to toss in the shelled edamame.
Return the tray to the oven for another 5 to 7 minutes until the vegetables are tender-crisp and the tofu is golden brown.
Transfer the roasted medley to a bowl, drizzle with the balsamic glaze, and finish by sprinkling with hemp seeds and nutritional yeast.
