Chicken Soup With Sweet Potato And Collard Greens

"My version of @shirabocar 's Chicken soup with sweet potatoes and collard greens. I used Kailan coz that's all I have in my fridge and it does make the soup even more asian-y. And I love the last addition of almond butter which give me that filling satisfaction slurp after slurp. "
