Heat 1-2 tbsp (15-30 ml) olive oil (or the oil from the sun-dried tomatoes) in a large skillet over medium-low heat. Add the frozen spinach, cover, and let it thaw and wilt for 4-5 minutes.
Drain the sun-dried tomatoes and cut them into small pieces. Uncover the pan, add the tomatoes, turn the heat up, and cook for another minute.
Crumble the tofu with your hands directly into the pan. Add the turmeric and salt to taste, and cook, stirring, for 2 to 3 minutes, until the tofu is hot and evenly golden.
Serve hot, sprinkled with the black and white sesame seeds.
