While this hearty vegetarian curry is great on it's own, you could serve it with some bread or over some rice or quinoa to make it more of a meal. Chopped swish chard or spinach could be substituted for the kale.
Place all ingredients except for kale into a slow cooker and cook on low for 8-10 hours.
After about 8-10 hours, turn slow cooker to warm and mix kale into stew. Place lid back on until kale has wilted.
Serve topped with a spoonful of Greek yogurt and some cilantro.
