When the cumin seeds splutter, add curry leaves, green chilis and sauté for a few seconds.
Add in shredded potatoes and 2 cups of water. Moreover, stir well.
Add the diced bell peppers and bring it to boil (approx. 5 minutes). Keep stirring intermittently.
Then, add the moriyo seeds, 2 more cups of water, turmeric and salt. Stir well.
Cook for 6-8 minutes or until desired consistency is reached. Keep stirring intermittently. Finally, garnish with cilantro and serve. It should have a consistency like sooji upma. Most of the water needs to be evaporated.
