Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Drain and rinse the chickpeas, then pat them very dry with a clean kitchen towel or paper towels to ensure they get crispy.
Cut the firm tofu into 1/2-inch cubes and pat dry to remove excess moisture.
In a large mixing bowl, combine the chickpeas, tofu cubes, and broccoli florets.
Drizzle with olive oil and sprinkle with nutritional yeast, sea salt, and black pepper, tossing until everything is evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 to 30 minutes, tossing halfway through, until the broccoli is charred and the chickpeas are crunchy.
While the vegetables roast, prepare the protein base by whisking together the Greek yogurt, lemon juice, and garlic powder in a small bowl until smooth.
Spread the lemon-garlic yogurt mixture onto the bottom of a shallow bowl.
Top the yogurt with the roasted vegetable and chickpea mixture.
Garnish with hemp seeds for extra texture and serve immediately.
