<human>:  What is a quinoa and how do you cook it?
<bot>: Quinoa is an ancient grain that is highly nutritious and versatile. It is a complete source of protein and contains all nine essential amino acids. It has a slightly nutty flavor and a light, fluffy texture when cooked. To cook quinoa, simply boil two parts water or broth to one part quinoa in a saucepan. Bring the mixture to a boil, then reduce the heat and let simmer for about 15 minutes. When the quinoa is cooked, it should be soft and the liquid should be completely absorbed. Fluff with a fork and serve.
