We have been using nutritional yeast flakes more often lately. It is actually a complete protein, which makes it easy to sneak protein into your diet! I love to make yeast butter to drizzle on veggies: we just melt 1-2 tablespoons of butter in the microwave, then stir in some yeast flakes. Here is a little blurb about it from Wikipedia: "It is a source of protein and vitamins, especially the B-complex vitamins and is a complete protein. It is also naturally low in fat and sodium... Nutritional yeast has a strong flavor that is described as nutty, cheesy, or creamy, which makes it popular as an ingredient in cheese substitutes. It is often used by vegans in place of parmesan cheese. Another popular use is as a topping for popcorn. It can also be used in mashed and fried potatoes, as well as putting it into scrambled eggs."
