Unless you've been living under a rock (or just thousands of miles from a Whole Foods), you probably have some sense of how good quinoa is for you. It's chock-full of protein, and it's super versatile. Case in point: This twist on cheese puffs. While this snack may stir fond memories of grade school lunches, unlike the junk food staple, it'll satisfy with protein and won't bog you down with empty calories.
