While potatoes are cooking, season the chicken with salt, pepper, and crushed red pepper.
Add 1 tablespoon olive oil in a skillet over medium heat. Add the chicken to the skillet and cook for 5 minutes or until it’s cooked through. Set aside.
In the same skillet, add onions and cook for five minutes or until onions start to soften. Then, add garlic and cook for one more minute.
Add bell peppers and sun-dried tomatoes and cook for 5 minutes.
Add spinach and sauté until it's all wilted and add the cooked chicken.
Cut the sweet potato in half lengthwise (without cutting them all the way down) and stuff them with the chicken spinach mixture.
Sprinkle the goat cheese on each sweet potato. Top with fresh parsley. Serve immediately.
