Drain the tofu block and blot it between paper towels, gently squeezing it to release as much water as possible.
To prepare the basic seasoning, combine tamari, turmeric, garlic, lemon juice, oregano, salt, pepper in a small bowl and whisk well.
In a large skillet over medium heat, sauté onions in olive oil until golden brown, approximately 8 minutes. Browning the onions adds time to prep this recipe, but I promise you it is totally worth it. Add red bell pepper and sauté for 2 minutes. Using a wooden spoon or a spatula, push the onions and bell peppers to the sides to create a cavity right in the center of the skillet. Break the tofu with your hands and add to the center of the skillet. Pour the seasoning mix over the tofu and stir to combine. Stir to combine it with all the other ingredients in the skillet and let it cook for 2 minutes. Remove from stove, add vegan mozzarella and stir to combine.
