Place the tofu pieces into a bowl with the turmeric, cumin, sweet, smoked paprika, nutritional yeast flakes, kala namak, salt, ground black pepper and mix together.
Heat the oil in a frying pan and add the tofu and spices. Heat on a medium heat for a few minutes while stirring to ensure even cooking.
While the tofu is cooking, place the sourdough in a toaster and toast to your liking.
When the toast is ready and the tofu heated through, add both to 2 plates with the avocado slices and tomato.
Serve immediately.
