Heat the olive oil in a large skillet over medium low heat.
Add the diced onions and bell pepper. Stir occasionally until the onions are beginning to soften and turn translucent, about four minutes.
Add the minced garlic to the onions and pepper and sauté one minute more.
Meanwhile, remove the tofu from its packaging and squeeze dry with a dish towel. (Note: If using a firm or super firm block, the tofu will not have to be pressed.)
Place the block in a large bowl and break up with the back of a fork until it resembles scrambled eggs.
Add the tofu to the skillet with the vegetables and stir.
Add the water and turmeric to a small bowl and stir until combined. Add the liquid to the skillet and stir and cook into the tofu until incorporated and heated through, about 2-3 minutes.
Add the nutritional yeast and salt and stir until combined.
Add cilantro if desired. Serve.
