Take a pan and roast vermicelli or semiya on a low flame for around 5 minutes.
Take all the ingredients into a mixing bowl - roasted vermicelli, rice flour, whole wheat flour, chopped onion, chopped methi leaves, green chili paste, ginger and garlic paste, cumin, salt.
Add water and curd to this bowl and mix it well. The batter should be of pouring consistency.
Now heat the dosa pan and add a tsp of oil. Pour a ladle full of semiya dosa batter and spread it slowly and evenly.
Cover it with a lid and cook on medium to low flame for 2 to 3 minutes.
Flip the vermicelli dosa and let it cook for a couple of more minutes on this side also.
Remove from the pan once the dosa is cooked well on both sides. Serve it hot!
