This is my favourite family recipe! My kids don't eat channa daal so I cheat and mush up the entire contents in a mxie or with a hand blender so they don't know the difference! I make a whole pressure cooker of it and take it to work as a soup. It tastes good with either rice or roti as well.
With rice or chapatis. You can skip the potatoe if you want less carbs in your meal.
