Dice the onion. Mash the tofu in the mixing bowl until it resembles the texture of scrambled eggs.
Heat the oil in a pan over medium heat. Add the onions and cook until slightly softened and golden, about 3 to 5 minutes.
Add the tofu to the pan along with the kala namak, turmeric, and nutritional yeast. Stir well to coat the tofu. Cook until the tofu is light and fluffy, about 3 to 5 minutes.
Add the black beans and salsa. Cook until the mixture is light and fluffy, about 3 to 5 minutes.
Notes
Turmeric adds a little more yellow color to the dish. It is fine to omit it.
