Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the tofu with a clean towel to remove excess moisture, then cut it into bite-sized cubes.
Spread the tofu, chickpeas, and broccoli florets onto the baking sheet in a single layer.
Drizzle with olive oil and season with sea salt, black pepper, and garlic powder, tossing to coat evenly.
Roast for 20 to 25 minutes, tossing halfway through, until the tofu is golden and the broccoli is tender.
In a small jar, whisk together the tahini and lemon juice with a teaspoon of warm water until it reaches a smooth, drizzling consistency.
Divide the cooked quinoa into bowls and top with the roasted vegetable and tofu mixture.
Garnish with pumpkin seeds and a generous sprinkle of nutritional yeast, then finish with the tahini dressing.
