Then sprinkle on half of the spice mixture and cook another minute, until fragrant.

Add the remaining spices and cook another minute until spices are fragrant. Throw in pumpkin and carrots and toss to coat. Then pour in broth and coconut milk. Bring to boil, then turn down heat and allow to simmer until pumpkin is fork tender but not mushy - about 18-20 minutes.Add chopped greens and cooked chicken and cook another 2-3 minutes- until greens are wilted.
