Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Pat the chickpeas and cubed tofu dry with a clean kitchen towel to ensure maximum crispiness during roasting.
In a large bowl, toss the chickpeas, tofu, and broccoli florets with olive oil, garlic powder, smoked paprika, sea salt, and black pepper.
Spread the mixture in a single layer on the prepared baking sheet and roast for 20-25 minutes, tossing halfway through, until the tofu is golden and chickpeas are crunchy.
While the vegetables roast, whisk together the tahini, lemon juice, and nutritional yeast in a small bowl, adding 1-2 tablespoons of warm water until the dressing is smooth and pourable.
To assemble, place the cooked quinoa in the bottom of a bowl and top with the roasted chickpea and vegetable mixture.
Drizzle the velvety tahini dressing over the top and serve immediately while warm.
