Dal adas is a traditional vegetarian dish hailing from the southern Iranian port city of Bushehr, located on the Persian Gulf. Reminiscent of an Indian dal, this dish typically consists of red lentils which are simmered in vegetable stock with sautéed onions and garlic, diced potatoes, tomato purée, and spices such as turmeric, cumin, cinnamon, chili powder, and salt.

The combination is enhanced with fresh lime juice or tamarind paste, and it can have a thin and soupy or thick and stew-like consistency. This spicy lentil soup or stew is generally served with freshly chopped coriander and red chili on top, and it's usually accompanied by Persian rice or warm bread on the side.
