The seeds need very little cooking. This time is especially short for lentils with their husk removed, such as the common red lentil. Lentils have a distinctive earthy flavor. They are used to prepare an inexpensive and nutritious soup all over Europe and North and South America. Sometimes they are combined with some form of chicken or pork. They are frequently combined with rice, which has a similar cooking time. In the Middle East such a dish of lentils and rice is called "mujaddara" or "mejadra". Rice and lentils are also cooked together in khichdi, a popular Indian dish. Lentils are used throughout India, the Mediterranean regions and the Middle East. In rare cases the lentils are mixed with dairy cheese.
