Cook the quinoa
Heat the oven to 350°F. In a medium pot, combine the quinoa, 1 cup of water and a pinch salt (double the water for 6 portions); bring to a boil. Cover and simmer, 14 to 16 minutes, until the quinoa is tender. Fluff with a fork. Meanwhile, peel the beets and cut in half; cut into ¼-inch-thick half-moons. Place in a small pot, cover with water and bring to a boil. Simmer, 7 to 9 minutes, until the beets are fork tender.
