A samosa is a fried or baked pastry with savoury filling, such as spiced potatoes, onions, peas, lentils and also with minced meat (lamb, beef or chicken), and sometimes pine nuts.

The samosa originated in the Central Asia. Its size and consistency may vary, but typically it is distinctly triangular or tetrahedral in shape.

Indian samosas are usually vegetarian, and often accompanied by a mint sauce or chutney. Vegetarian samosas originated in Uttar Pradesh.
