Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu to remove excess moisture, then cut it into even 1/2-inch cubes.
Place the tofu cubes, chickpeas, and broccoli florets on the baking sheet; drizzle with olive oil and season with sea salt, black pepper, and garlic powder.
Toss the vegetables and protein until evenly coated, then roast in the oven for 20-25 minutes until the tofu is golden and the broccoli is tender.
While the vegetables roast, place the chopped kale in a small bowl and massage it with a splash of lemon juice for 1 minute until it softens.
In a small ramekin, whisk together the tahini, remaining lemon juice, and water until a smooth, pourable dressing forms.
Assemble the bowl by layering the cooked quinoa and massaged kale at the base.
Top with the roasted tofu, chickpeas, and broccoli, then sprinkle generously with nutritional yeast and hemp hearts.
Drizzle the lemon-tahini dressing over the entire bowl and serve immediately.
