A native of the southern United States and Northern Mexico, pecans are tree nuts. Known for their rich flavor, pecans contain a variety of nutrients, including plenty of protein, iron, and B vitamins. Not only are pecans good for you, but they also make delicious additions to both sweet and savory dishes. Roasted pecans are also hearty snacks on their own. If you love nuts and have a sweet tooth, consider purchasing honey roasted pecans, which will also satisfy a craving for salt.
