A samosa is a savoury Indian snack that is traditionally made with a fried or baked pastry shell filled with a savoury filling, such as spiced potatoes, onions, peas, and lentils. It is usually served as an appetizer or snack, and is often accompanied by chutney or other dipping sauces. Samosas are popular in many parts of the world, including India, Pakistan, Bangladesh, Nepal, and Sri Lanka.
