Add chopped tomatoes and cook until they turn soft.

Add the boiled and mashed potatoes, salt, and coriander leaves. Mix well and cook for 2-3 minutes. Turn off the flame.

Heat a tawa or griddle over medium heat. Spread a ladle full of dosa batter in a circular motion to form a thin layer.

Place a spoonful of the potato mixture on one side of the dosa and fold it.

Cook the dosa for 1-2 minutes on both sides until it turns golden brown.
