Take 1 cup of Rava or semolina and dry roast in a flat pan. It won’t take more than 3-4 mins. After 3 mins when it's fragrant remove from heat and transfer to a dry plate.
Heat 3 - 4 tbsp refined oil. Once the oil is hot put mustard seeds and let them splutter. You can add a pinch of cumin seeds also with it.
After that put lentils, curry leaf, ginger, green chilli and onion into it. Saute for a minute. Don’t over heat else onions will turn brown.
Add sliced tomatoes. Add all chopped vegetables and saute for 5 minutes on medium heat. Cover with a lid.
Then add 3 cups of water and get them to a boil. Add salt as required or as per taste.
You can add a pinch of turmeric powder too if you want to give different color to it. However this is optional.
Simmer for 5 minutes on low film.
Once vegetables are cooked well, add roasted semolina into pan gradually & slowly. Stir continuously to avoid lumps inside.
Let it simmer for 3 – 4 mins more & get cooked properly. Simmer till all water is soaked up.
In the end you can add few drops of lemon and few coriander leaves.
Remove from heat and cover with a lid for 2 - 3 minutes.
