The term 'Polynesian Staple Food' is often associated with the three-letter word 'Poi'. Poi is a traditional Polynesian food made from taro root, which is mashed and mixed with water to create a thick paste. It is a staple food in many Polynesian cultures and is often served as an accompaniment to other dishes. Poi is also known for its health benefits, as it is high in carbohydrates and low in fat.
