Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Drain the extra-firm tofu and press it between paper towels for 10 minutes to remove excess moisture, then cut into 1/2-inch cubes.
In a large mixing bowl, combine the tofu cubes, broccoli florets, and diced red bell pepper.
Drizzle with avocado oil and tamari, then sprinkle with garlic powder, sea salt, and black pepper, tossing until everything is evenly coated.
Spread the tofu and vegetables in a single layer on the prepared baking sheet and roast for 20 to 25 minutes, flipping halfway through, until the tofu is golden and the broccoli is slightly charred.
While the vegetables roast, steam the shelled edamame for 3 to 5 minutes until tender and bright green.
In a large serving bowl, combine the warm cooked quinoa, roasted tofu, roasted vegetables, and steamed edamame.
Drizzle the lemon juice over the bowl and sprinkle with nutritional yeast, tossing gently to combine all the flavors before serving.
