Heat a greased tawa until hot.
Pour 1 ladle of batter and spread it slightly thick towards the edges. Allow to cook for 1 min.
Pour the egg and break the yolk. Spread the yolk around the dosa.
Add the veggies evenly. Cook until the base firms. Add oil around the edges.
Flip it and press gently with a wooden spoon to ensure egg is cooked well.
Flip back and cook until the dosa turns crisp.
