An ancient "grain" native to South America, quinoa has been cultivated in the Andean mountain regions of Peru, Chile and Bolivia for over 5,000 years, and it has long been a staple food in the diets of the native Indians. The Incas considered it a sacred food and referred to it as the "mother seed." Not only is quinoa high in protein, but the protein it supplies is complete protein, meaning that it includes all nine essential amino acids. Not only is quinoa's amino acid profile well balanced, making it a good choice for vegans concerned about adequate protein intake, but quinoa is especially well-endowed with the amino acid lysine, which is essential for tissue growth and repair. In addition to protein, quinoa features a host of other health-building nutrients. Because quinoa is a very good source of manganese as well as a good source of magnesium, iron, copper and phosphorus, this "grain" may be especially valuable for persons with migraine headaches, diabetes and atherosclerosis.
We usually think of quinoa as a grain, but it is actually the seed of a plant that, as its scientific name Chenopodium quinoa reflects, is related to beets, chard and spinach. These amino acid-rich seeds are not only very nutritious, but also very delicious. Cooked quinoa seeds are fluffy and creamy, yet slightly crunchy. They have a delicate, somewhat nutty flavor. While the most popular type of quinoa is a transparent yellow color, other varieties feature colors such as orange, pink, red, purple or black.
Black-Bean and Tomato Quinoa Adapted from Gourmet | July 2007
Quinoa is a fast-cooking, protein-packed whole grain. Steamed, it makes a perfect partner for lime-spiked black beans and fresh tomato.
2 teaspoons grated lime zest
2 tablespoons fresh lime juice
2 tablespoons unsalted butter, melted and cooled
1 tablespoon vegetable oil
1 teaspoon sugar
1 cup quinoa
1 (14- to 15-ounce) can black beans, rinsed and drained
2 medium tomatoes, diced
4 scallions, chopped
1/4 cup chopped fresh cilantro
Whisk together lime zest and juice, butter, oil, sugar, 1/2 teaspoon salt, and 1/4teaspoon pepper in a large bowl.
Wash quinoa in 3 changes of cold water in a bowl, draining in a sieve each time.
Cook quinoa in a medium pot of boiling salted water (1 tablespoon salt for 2 quarts water), uncovered, until almost tender, about 10 minutes. Drain in sieve, then set sieve in same pot with 1 inch of simmering water (water should not touch bottom of sieve). Cover quinoa with a folded kitchen towel, then cover sieve with a lid (don't worry if lid doesn't fit tightly) and steam over medium heat until tender, fluffy, and dry, about 10 minutes. Remove pot from heat and remove lid. Let stand, still covered with towel, 5 minutes.
Add quinoa to dressing and toss until dressing is absorbed, then stir in remaining ingredients and salt and pepper to taste.
