Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Press the extra firm tofu with a heavy object for 10 minutes to remove excess moisture, then cut into 1-inch cubes.
Rinse and drain the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure they get crispy.
Place the tofu cubes, chickpeas, and broccoli florets on the prepared baking sheet and drizzle with the olive oil.
Sprinkle the sea salt, black pepper, and garlic powder over the vegetables and protein, tossing well to coat everything evenly.
Roast in the oven for 25 minutes, flipping the ingredients halfway through, until the tofu is golden and the chickpeas are slightly crunchy.
While the vegetables roast, simmer the quinoa in water according to package directions until fluffy and the water is absorbed.
Assemble the Buddha bowl by placing the cooked quinoa in the base and topping it with the roasted tofu, chickpeas, and broccoli.
Garnish the bowl with nutritional yeast and hemp seeds, then finish with a bright squeeze of fresh lemon juice before serving.
