Dice the chicken breast into bite-sized nuggets and peel/cube the russet potato into half-inch pieces.
In a bowl, toss the potato cubes with half of the olive oil, sea salt, black pepper, and garlic powder.
Place the potatoes in the air fryer basket and cook at 400°F (200°C) for 12-15 minutes, shaking halfway through, until golden and crisp.
While potatoes cook, toss the chicken nuggets in the remaining olive oil and seasonings.
Remove the potatoes and keep warm, then add the chicken to the air fryer and cook at 400°F (200°C) for 8-10 minutes until cooked through.
In a small bowl, whisk together the honey, apple cider vinegar, and tamari to create the clean Polynesian sauce.
In a small non-stick skillet, whisk the egg and scramble over medium-low heat until just set.
Assemble the bowl by layering the scrambled egg at the bottom, followed by the crispy potatoes and chicken nuggets.
Top with shredded cheddar cheese while hot so it melts, then drizzle with the Polynesian sauce and garnish with fresh parsley.
