Put the carrots, onion, lentils, broth, garlic, spices, salt and pepper in a large Crock Pot and stir together. Cook on low for 8 hours or high for 4 hours or until the lentils are tender. Depedning on how much broth the absorb, add a touch more broth.
Once cooked reduce heat to warm and stir in the kale until it is wilted. Squeeze the fresh lemon on top.
Remove the bay leaves and serve!
The pinch of red pepper does make it hot, just adds some flavor.
