In a bowl, wash lentils and rice until water runs clear.
Add them to a cooking pot with 5-6 cups of water. Let it simmer on medium heat for 15 to 20 minutes. You can also pressure cook lentils for 10 minutes.
Once the lentil and rice are mushy, blend them in the blender or with an emergent blender. You can add 1 to 2 cups of water if the mixture is too thick; this will help with the consistency and it ease the blending process.
In a separate saucepan, heat the oil and sauté the chopped onion until translucent.
Take the pan off the heat and add curry powder and turmeric powder. Mix them and cook the mixture on low heat for a minute while stirring.
Now add the onion mixture and salt to the lentil mixture.
Let it simmer on medium heat for 5 to 10 minutes until it thickens to the desired consistency. Do stir occasionally to avoid sticking and burning.
Serve it hot with a sprinkle of parsley and a wedge of lemon.
