Move the chicken to slow cooker.
Add onion to the same pan and saute until translucent.
Add garlic and saute for 1 to 2 minutes.
Transfer onion and garlic to the slow cooker.
Add the tomatoes, chili peppers, almond butter, dark chocolate, salt and spices to the slow cooker.
Cook on low to 4 to 6 hours or until the chicken is tender and pulls apart easily.
