Preheat oven to 400°F and line a large baking sheet with parchment paper.
Drain and rinse the chickpeas and pat them dry with a clean towel to ensure they become crispy.
Press the tofu to remove excess moisture, then cut into small half-inch cubes.
Place the chickpeas, tofu cubes, and broccoli florets on the prepared baking sheet.
Drizzle with olive oil and season with sea salt, black pepper, and garlic powder.
Toss everything together until evenly coated, then spread in a single layer.
Roast for 25-30 minutes, tossing halfway through, until the chickpeas are golden and the broccoli is tender.
Remove from the oven and immediately sprinkle with nutritional yeast and hemp hearts while still hot.
Drizzle with fresh lemon juice before serving in a large bowl.
