Press the firm tofu between paper towels for 10 minutes to remove excess moisture, then cut into 1-inch cubes.
Heat the olive oil in a large skillet over medium-high heat and sear the tofu cubes until golden brown on all sides.
Add the minced garlic and grated ginger to the pan, sautéing for 1 minute until fragrant.
Stir in the ground turmeric, cumin, coriander, sea salt, and black pepper to toast the spices for 30 seconds.
Pour in the tomato puree, chickpeas, cauliflower florets, and water, then stir to combine.
Reduce heat to medium-low, cover, and simmer for 8-10 minutes until the cauliflower is fork-tender.
Remove the lid and stir in the fresh spinach, cooking for 1-2 minutes until the leaves are perfectly wilted.
