Heat the broth in a large pot, until it is simmering mildly. Add in the butter, coconut oil, basil, and allspice.
After heating the oven to 450 F, cook the sirloin until done (20-30 minutes). Remove the sirloin and place in the large pot. Once fully cooked and mixed, add in the kale, and mix well.
Ladle out soup, serve in bowls, and enjoy!
