Mung bean sprouts, or togue in Filipino, is one of the cheapest vegetables in the local market. Probably one of the reasons for the cheap price is that togue is easy to cultivate. The mung beans, or mongo, sprout from two to five days. I know this for a fact because it was a popular science project in grade school. Planting mongo seeds and watching their development for the next couple of days. There was even an experiment when the seeds were placed in jars full of water, sandwiched between the interior of the jar and a sheet of litmus paper to hold the seeds steady. So, anyway, below is what togue, or mung bean sprouts look like before they are cooked.
According to one site, this vegetable is rich in Vitamins A, B, C and E, Calcium, Iron, Magnesium, Potassium and Amino Acids. According to another site, a cup of mung bean sprouts contain a mere 26 calories.
