Despite the name, wild rice isn't technically a type of rice, but rather the seed of an aquatic grass. However, that shouldn't stop you from leaning on it as a yummy side dish. One cup of wild rice contains 6.5 grams of protein along with almost 3 grams of fibre and a slew of micronutrients. While the protein content of wild rice may be relatively low, it is still a noteworthy option, as it supplies all of the essential amino acids the body needs, making it a complete protein choice.
