Dice the chicken breast and sweet potato into small, uniform 1/2-inch cubes to ensure even cooking.
Heat the extra virgin olive oil in a large skillet over medium-high heat.
Add the sweet potato cubes to the skillet and cook for 8-10 minutes, stirring occasionally, until they are softened and slightly browned.
Stir in the diced yellow onion and red bell pepper, sautéing for about 3 minutes until the vegetables are fragrant and tender.
Add the diced chicken breast, smoked paprika, garlic powder, sea salt, and black pepper to the pan.
Cook for another 5-7 minutes, stirring frequently, until the chicken is cooked through and the hash develops a golden, crispy exterior.
Remove from heat and garnish with chopped fresh parsley before serving.
