1Boil the potatoes until they are soft. Peel and mash them.
Heat 5g of oil in a pan. Add chopped onions, green chili, ginger, and garlic. Sauté until the onions are translucent.
Add the mashed potatoes and masala to the pan. Mix well and cook for 5 minutes. Set aside.
In a bowl, mix maida with water to form a smooth batter.
Heat a non-stick pan and grease it lightly with oil.
Pour a ladleful of batter onto the pan and spread it in a circular motion to form a thin dosa.
Cook the dosa until the edges start to lift. Place a portion of the potato masala in the center.
Fold the dosa over the masala and cook for another minute.
Serve hot with chutney or sambar.
