Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Dice the sweet potato into half-inch cubes and press the extra firm tofu with a towel to remove moisture before cutting into matching cubes.
Spread the sweet potato, tofu cubes, and drained chickpeas across the prepared baking sheet in a single layer.
Drizzle the olive oil over the mixture and sprinkle evenly with ground turmeric, ground ginger, sea salt, and black pepper.
Toss everything thoroughly to ensure the anti-inflammatory spices are well-distributed across the ingredients.
Roast for 25 to 30 minutes, giving the pan a good shake halfway through, until the potatoes are tender and the tofu is lightly crisped.
Place the fresh baby spinach in a large serving bowl and pile the warm roasted vegetables and protein on top.
Finish the bowl by dusting it with nutritional yeast for a cheesy flavor and drizzling with fresh lemon juice to brighten the dish.
