Potatoes are a type of root vegetable that are native to the Americas and are a staple in many diets around the world. Root Vegetables are any type of vegetable that grows underground, such as carrots, beets, and turnips. All three of these vegetables are considered to be tasty and can be used in a variety of dishes.
