Easy Tomato Soup

Heat butter on slow heat and add the onions, chopped tomatoes, water, salt and green chillies.

Bring it to simmer and cook for around 40 minutes. Take it off the pan and pour it into a blender and blend it. Be extra careful when doing this as it's very hot, not to burn yourself.

Pour the mixture into a pan and season with cumin powder. Ready to serve.
