Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Pat the firm tofu dry with paper towels to remove excess moisture and cut into 1-inch cubes.
In a large mixing bowl, toss the tofu cubes, cauliflower florets, and diced bell pepper with olive oil, ground turmeric, ground cumin, sea salt, and black pepper until evenly coated.
Spread the seasoned vegetables and tofu in a single layer on the prepared baking sheet and roast for 20-25 minutes until the cauliflower is tender and the tofu edges are golden brown.
While the vegetables roast, whisk together the nonfat Greek yogurt, red curry paste, and water in a small bowl until the sauce is smooth and combined.
In a large skillet over low heat, add the cooked chickpeas and the roasted vegetable and tofu mixture.
Pour the yogurt curry sauce over the ingredients and stir gently for 1-2 minutes until just heated through, ensuring the sauce does not reach a boil to prevent the yogurt from curdling.
Garnish with fresh cilantro and serve immediately.
