Heat a pan with ghee, add rava and roast on low flame until you get a nice aroma.
Transfer the roasted Rava on to the plate and keep aside.
Chop green chillies into halves and keep aside.
Heat the same pan which we used to roast the Rava with oil, add mustard seeds, urad dal, chana dal, cumin seeds, cashew nuts and saute for a minute.
Add chopped onions along with green chillies and fry until onion changes its colour.
Add 2cups of water to the pan along with salt and bring it to boil.
Slowly add the roasted rave and mix it without any lumps in it.
Cover and cook until all the water is evaporated or rava is cooked
Finally, add 1tsp of ghee on to umpa and switch off the flame.
Transfer into a serving plate and enjoy this delicious and easy rava upma with sambar or chutney.
