The green pea is one of the most popular vegetables. In addition to being quite nutritious, they are also a good source of fiber and antioxidants. In spite of the fact that green peas are commonly marketed as vegetables, they are actually legumes. Due to green peas' high fiber and protein content, they are among the most filling plant-based foods. Companies also supply this vegetable in frozen form, so that people can use it in soups, snacks and curry even in non-seasonal months.
