Preheat your air fryer to 400°F (200°C).
Dice the chicken breast and sweet potato into uniform 1/2-inch cubes to ensure even cooking.
In a large mixing bowl, combine the diced chicken, sweet potato, chopped bell peppers, and red onion.
Drizzle with 1 tablespoon of olive oil and sprinkle with smoked paprika, garlic powder, sea salt, and black pepper; toss thoroughly to coat.
Transfer the mixture to the air fryer basket, spreading it out in an even layer.
Air fry for 15 to 18 minutes, shaking the basket every 5 minutes, until the chicken is cooked through and the sweet potatoes are tender and browned.
While the hash is air-frying, heat the remaining 0.5 tablespoon of olive oil in a small non-stick skillet over medium heat and fry the egg to your preferred doneness.
Plate the hot hash and top with the fried egg, sliced avocado, and a garnish of fresh parsley.
