Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Drain and rinse the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure they get crispy.
Press the extra firm tofu for 10 minutes to remove excess moisture, then cut into uniform 1/2-inch cubes.
In a large mixing bowl, toss the chickpeas, tofu cubes, and broccoli florets with olive oil, garlic powder, smoked paprika, sea salt, and black pepper.
Spread the mixture in a single layer on the baking sheet and roast for 25 minutes, tossing halfway through, until the tofu is golden and chickpeas are crunchy.
Whisk the tahini and lemon juice together in a small ramekin, adding a few drops of water until the dressing reaches a pourable consistency.
Place the warm cooked quinoa in the base of a bowl and top with the roasted vegetable and protein mixture.
Finish the bowl by sprinkling with nutritional yeast and hemp hearts, then drizzle the lemon-tahini dressing over the top.
