Green beans, originally from Mexico and Peru and brought to Spain in the 16th century, are the tender pods of dry beans, belonging to the Fabaceae family. There are various varieties, such as the Perona, characterized by being wide and long, ideal for cooking. These vegetables, with 90% water content, are very low in calories, high in fiber, and contain multiple vitamins and minerals, making them a favorable food in healthy diets. Additionally, they offer benefits for the immune system and are recommended for those suffering from high cholesterol or kidney issues. For storage, it is recommended to keep them in a perforated bag in the fridge to maintain freshness over the week. Green beans are versatile in the kitchen: they can be boiled, grilled, or used in salads and side dishes. Their crunchy texture and flavor make them a perfect side for meat and fish.
