Kale Potato Stir-fry (Aloo Kale Sabzi)

This is the first time I'm trying kale (curly leaved Scots kale) and it tastes very similar to collard greens that I tried recently. This made me think, once wilted does all greens taste the same? Not really, huh! Potato and kale got together very nicely just like potato and spinach. The recipe that I followed calls for grinding roasted chana dal and coconut for gravy, but I left them as such because I wanted to make a crunchy dry curry.
