The phrase "grain quinoa" typically refers to a type of food made from the grains of the quinoa plant. Quinoa is a pseudocereal that originated in South America and has become increasingly popular as a healthy alternative to traditional cereals like rice or wheat. When cooked, the individual grains of quinoa expand and have a slightly crunchy texture, making it a versatile ingredient for dishes such as salads, pilafs, and side dishes.
