Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the firm tofu between paper towels to remove excess moisture, then cut into 1-inch cubes.
Slice the zucchini into half-moons and ensure the cauliflower is cut into bite-sized florets.
In a large mixing bowl, combine the tofu cubes, chickpeas, cauliflower, and zucchini.
Drizzle with avocado oil and sprinkle with turmeric, ground cumin, sea salt, and black pepper, tossing until every piece is evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 to 30 minutes until the vegetables are tender and the tofu is slightly crisp.
Place the warm cooked millet in a serving bowl and top with the roasted vegetable and protein mixture.
Finish the bowl by sprinkling with nutritional yeast and a fresh squeeze of lemon juice before serving.
