Pressure cook red lentils until cooked through and mushy. Alternately red lentils can be cooked on the stove top until tender.
Heat oil in a saucepan, add the chopped onions and cook until they are golden brown. Add 1 tbsp masala powder, mix well and cook for 1~2 minutes.
Stir in the cooked dal, turmeric and salt. Add water if the dal looks too thick. Simmer on medium flame for 6~8 minutes.
Sprinkle chopped cilantro and serve with steamed plain rice.
