Heat 1/4 cup of water (60 ml) in a large skillet over medium heat. Add the onion, then cover and cook until tender, about 5 minutes. Add the bell pepper and cauliflower, then cover and cook, stirring occasionally, until tender, about 5 minutes. Stir in the mushrooms, nutritional yeast, Dr. Greger’s Special Spice Blend, and turmeric. Cover and cook for 5 minutes. While the veggies are cooking, mash the chickpeas and add them to the skillet. Cover and cook, stirring occasionally, until heated through and any liquid is absorbed, about 5 minutes longer. Top with the parsley and any optional topping you prefer (see head note), and serve hot.
