For many years green peas have been known as a garden or countryside vegetable. In fact, they still are. Some even consider green peas a fruit due to their seed reference. Any vegetable that contains seeds, like tomatoes, are considered and deemed a fruit, but for green peas, many tales have been told.  Strictly speaking, they are part of the legume family as they grow like other legumes such as chickpeas and lentils. Green peas are from a plant that produces pods, which is where the pea is from, just like other legume. Today, green peas are still cooked and served as a vegetable but they are indeed a legume.
