Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the firm tofu with a heavy object for 10 minutes to remove excess moisture, then cut into 1/2-inch cubes.
Rinse and drain the chickpeas, then pat them dry with a clean kitchen towel to ensure they get crispy.
In a large mixing bowl, combine the tofu cubes, chickpeas, and broccoli florets.
Drizzle the mixture with olive oil and sprinkle with garlic powder, sea salt, black pepper, and 2 tablespoons of the nutritional yeast.
Toss everything together until evenly coated, then spread in a single layer on the prepared baking sheet.
Roast for 25-30 minutes, tossing halfway through, until the tofu is golden and the chickpeas are slightly crunchy.
Transfer the roasted mixture to a serving bowl and top with the remaining 1 tablespoon of nutritional yeast, hemp seeds, and a fresh squeeze of lemon juice.
