Tomato Paste is any of a very large number of sauces made primarily from tomatoes, usually to be served as part of a dish (rather than as a condiment). Tomato sauces are common for meat and vegetables, but they are perhaps best known as sauces for pasta dishes.

       Tomatoes have a rich flavour, high liquid content, very soft flesh which breaks down easily, and the right composition to thicken into a sauce when they are cooked (without the need of thickeners like roux). All of these qualities make them ideal for simple and appealing sauces. The simplest tomato paste consist just of chopped tomato flesh cooked in a little olive oil and simmered until it loses its raw flavour, and seasoned with salt.
