Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu with a heavy object for 10 minutes to remove excess moisture, then cut into 1-inch cubes.
In a mixing bowl, toss the tofu cubes, broccoli florets, and chickpeas with tamari, garlic powder, sea salt, and black pepper.
Spread the tofu and vegetable mixture onto the prepared baking sheet in a single layer.
Roast for 25 minutes, flipping the tofu halfway through, until the edges are golden and the broccoli is tender.
While roasting, whisk together the tahini, nutritional yeast, and lemon juice in a small bowl, adding a teaspoon of water at a time until it reaches a smooth, pourable consistency.
Assemble the bowl by placing the cooked quinoa and edamame at the base, topping with the roasted tofu and vegetables.
Drizzle the creamy tahini dressing over the top and serve immediately.
