Chop up the tofu into small pieces, heat the oil in a large pan then add the tofu and saute for a couple of minutes before mixing in the salt. Next, sprinkle in the turmeric powder and saute for 5 minutes. Then remove the tofu from the pan and set aside. Add the onion to the pan and if needed add a splash of olive oil, cook onion until soft. Mix in the garlic then add the serrano slices and then the chopped tomato. Cook until the tomato has begun breaking down, then mix in the cooked tofu and stir until well combined. Add the corn chips and stir until they are coated with the tofu mixture. Cook until the chips have softened. Serve with refried beans, salsa, and/or avocado slices. Enjoy as breakfast, or lunch or brunch or even dinner.
