Sarson Ka Saag

Sarson Da Saag (as it is known in Punjabi) or (Sarson Ka Saag, in Urdu) is a popular vegetarian dish from the Punjab region of South Asia. It is made from mustard greens (sarson) and spices such as ginger and garlic. It is often served with makki di roti.
Origins and history
The dish is regarded as the traditional way to prepare saag and is usually served with makki di roti. It can be topped with either Makkhan (unprocessed white butter or processed yellow butter) or more traditionally with ghee (clarified butter). Some spinach (called palak ) may be added to enhance colour and thicken the dish, though this may alter the flavor. Also added are some bathua, sarson greens, onion, tomato and all ground spice.
Mustard is a winter and spring delicacy, and its relative abundance in Punjab has made it one of the most popular dishes in those regions.
