Beetroot sabzi - in slow cooker

Super healthy and exciting recipe. Chop few beet roots (4-5 medium six) into cubes. Chop some onions and one large tomato. In a pan, take one spoon of olive oil.  Add 1 dried tej patta, 3-4 cloves, 3-4 whole black pepper, add onions - let it become golden. Add about 1 inch cinnamon stick; add the chopped tomatoes and add it to the pan. Add some grated ginger. After 1-2 min, add about one cup of water (or even less than that). Put this "gravy" and the beetroots in the slow cooker. Keep it on high for 4 hours. The dish came out so good. I used mostly all organic ingredients and that must have helped too. Milosh loved it also!
I served it methi dal and quinoa/ millet mix.
