Crumble the block of extra firm tofu directly into the pan, breaking it apart with a spatula into bite-sized pieces so it resembles scrambled eggs.
Sprinkle the nutritional yeast, turmeric, garlic powder, and kala namak (or sea salt) over the crumbled tofu. Stir thoroughly to ensure the tofu is evenly coated and turns golden yellow. Cook for 5 minutes.
Stir in the rinsed black beans and fresh spinach. Continue to cook for 2-3 minutes, stirring frequently, until the spinach is fully wilted and the beans are heated through.
Remove the skillet from the heat. Divide the scramble into two bowls and serve immediately.
