Preheat oven to 425 degrees F. Individually wrap the sweet potatoes in foil, then place on the oven rack and bake for 45 minutes to 1 hour, depending on the size of your sweet potatoes. You'll know they're done when you gently press the side of one, and it's very soft. Remove from oven and set aside.
Season chicken with the garlic powder, onions powder, paprika, and salt/pepper. Add olive oil in the bottom of a medium skillet, and heat over medium-high heat. Add chicken and cook for about 3-5 minutes on each side until done. Add in pecans, cranberries, and onions then toss to combine.
Halve each potato, and top each potato with a hefty portion of the cranberry pecan chicken mixture. Top with fresh rosemary and serve!
