Wash and chop mustard greens, spinach, and bathua, then boil them until tender.
Blend the cooked greens into a coarse paste.
Heat ghee in a pan and sauté ginger, garlic, onions, and green chilies until aromatic.
Add the blended greens, spices, and simmer for 20–30 minutes until thick and flavorful.
For the roti, knead maize flour with warm water into a soft dough.
Roll the dough carefully into flatbreads and cook on a hot griddle until golden on both sides, brushing with ghee.
