Heat a soup pot over medium high heat
Add the chicken thighs and brown on both sides 2-3 minutes
(If you are using chicken breasts, you may want to use a little oil in the pan)
Add the cubed sweet potatoes
Sprinkle with the cumin, chili powder and salt
Mix well until everything is coated with the spices
Cover with your broth (enough so there is at least an inch of liquid above the ingredients)
Bring to a boil
Lower to simmer and cover
Simmer for a minimum of 25 minutes (or until the sweet potatoes are soft and the chicken is cooked through)
Turn the heat off and immediately stir in your spinach
Serve with toppings of choice!
