Native to Mexico and the mountains of Central America, the Scarlet runner shelling bean plant produces thick skinned pods that are slightly fuzzy and vibrant green. Besides, these pods house striking, large, kidney-shaped seeds that are known for their vibrant colors. These runner beans can be simmered, sautéed, braised, fried, roasted, and steamed. And when it comes to their nutritional profile, they offer some iron, magnesium and calcium. In addition, runner beans in general contain folate, which helps prevent neural tube defects and other birth defects.
