Spring Onion, also known as Ulli Thand, is a fresh and mildly pungent vegetable widely used in cooking for its crisp texture and aromatic flavor. Both the green tops and white bulbs are edible and commonly added to stir-fries, salads, soups, noodles, and garnishes. Spring onions are rich in vitamins A, C, and K, antioxidants, and dietary fiber, supporting immunity, digestion, and overall health. They add freshness, color, and a subtle onion flavor to a variety of dishes.
