Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu for 15 minutes to remove excess moisture, then cut it into 1-inch cubes.
In a large mixing bowl, toss the tofu cubes, broccoli florets, and sliced red bell pepper with sesame oil, garlic powder, sea salt, and black pepper.
Spread the tofu and vegetable mixture in a single layer on the prepared baking sheet.
Roast for 25 minutes, flipping the tofu halfway through, until the edges are golden and crispy.
While the tofu roasts, whisk together the hoisin sauce and tamari in a small bowl.
Add the shelled edamame to the baking sheet during the final 5 minutes of roasting time.
Remove the sheet from the oven, drizzle the hoisin mixture over the roasted ingredients, and toss gently to coat.
Garnish with sesame seeds and serve immediately.
