Beetroot and potatoes in coconut gravey

I had a couple of beetroots languishing in the fridge, aand wanted to make something "different" with them. Checked on the internet, and couldn't find anything that was "just right", so decided to just throw together tastes I thought might work, and this was the result.

2 beetroots, cut into cubes
2 medium potatoes cut into cubes
4 tbsp grated coconut
1 green chilli
1 tsp saunf
salt to taste

For tempering
1/2 tsp mustard seeds
1 sprig curry leaves
oil

Method
Steam the cubed beetroots and potatoes till soft.
Grind the coconut, green chilli and saunf in the mixer till you get a smooth paste.
Heat the oil, add mustard seeds and curry leaves. When the mustard seeds start to splutter, add the ground masala, and cook it till the the coconut starts browning. Add the steamed vegetables, and water. Cover, and let it cook.
Serve hot with rotis.
