. Place sweet potatoes straight on to oven grates and bake until tender, approx. 45 minutes. (See above for additional preparation options).
In a medium bowl, combine spices and olive oil.
Place in chicken and stir to coat While sweet potatoes are cooking, bake chicken breasts on a small baking dish alongside them. The chicken breasts will take about half the time as the sweet potatoes to cook, so pull them out when they reach 165 degrees.
Once cool enough to handle, dice seasoned chicken into bite size pieces.
Prep toppings by dicing red onion, rinsing cooked black beans, slicing jalapeno and avocado, and quartering lime.
Slice sweet potatoes lengthwise, and top with listed toppings as desired.
