Preheat your oven to 400°F (200°C).
In a mixing bowl, toss the cubed sweet potatoes with 1 tablespoon of olive oil along with garlic powder, paprika, salt, and pepper. Spread them out on a baking sheet in a single layer.
Place the baking sheet in the preheated oven and roast for approximately 25 minutes or until the sweet potatoes are fork-tender.
Heat the remaining tablespoon of olive oil in a skillet over medium heat. Add diced chicken breast seasoned with salt and pepper; cook for about 7-10 minutes until fully cooked through.
In a large mixing bowl, combine the cooked rice with roasted sweet potatoes and chicken pieces. Mix everything together gently until evenly distributed.
Garnish your Chicken and Sweet Potato Rice Bowl with freshly chopped parsley before serving.
