Pea pods are the protective shells that contain peas, which are small, round seeds. These pods grow on pea plants, which are climbing plants that thrive in cool weather. Each pod typically holds several peas, and they can be eaten fresh, cooked, or dried. The pods themselves are usually green and can vary in size and shape. They are often harvested when young and tender for a sweet flavor. Snow peas and sugar snap peas are popular varieties that are eaten whole, while other types are shelled to enjoy the peas inside.
