Preheat your oven to 425°F and line a baking sheet with parchment paper.
Slice the potato into thin, even wedges and toss them in a bowl with olive oil, sea salt, black pepper, and garlic powder.
Spread the potato wedges in a single layer on the baking sheet and roast for 25 minutes, flipping halfway through, until golden and crispy.
While the potatoes roast, grill or pan-sear the chicken breast until the internal temperature reaches 165°F, and cook the bacon until crisp.
Dice the cooked chicken into small pieces and crumble the bacon into bits.
Remove the potatoes from the oven and pile them together, then top with the diced chicken, bacon, and shredded cheddar cheese.
Return the tray to the oven for 2 to 3 minutes until the cheese is completely melted and bubbly.
Garnish with thinly sliced green onions and serve immediately.
