Mix well and cook on medium heat for about 5 minutes or until the leaves become soft and are slightly cooked.
Stir in salt to taste and while on the stove, mash using a pav bhaji masher until the mixture is pulpy, and the dal and greens have mixed well. You can also blitz with an immersion blender (or regular blender) but I love to see flecks of greens in my curries!
Add more water (1/2 to 1 cup) depending upon how thick or thin you want your curry.
