Chayote (pronounced chahy-oh-tee) is a light green, pear-shaped fruit with a single, large pit and edible flesh and skin. The flesh of the chayote is mild in flavor. It has a texture somewhere in between a potato and cucumber.  Chayote (also affectionately known as cho-cho) is high in antioxidants and vitamins-specifically vitamin B, vitamin C, potassium, and amino acids.
