Swiss chard is a broad-leaved vegetable originating from the Vega de Aranjuez, San Martín de la Vega, and Ciempozuelos. It is highly valued for its flavor, which is more intense compared to spinach. Both leaves and stalks can be eaten, making it a versatile ingredient in the kitchen. It is rich in nutritional value, including protein, calcium, iron, and vitamins. It is recommended to enjoy it boiled, often paired with boiled potatoes and AOVE, or sautéed with potatoes and paprika, to which pine nuts can be added for a special touch. However, it's essential to note that Swiss chard has a short shelf life and is best consumed within 1-2 days of purchase. For increased freshness, store it in the fridge in a container covered with damp paper or lightly sprayed with water.
