Preheat your oven to 425°F (220°C) and line a small baking sheet with parchment paper.
Dice the yellow potato into small 1/2-inch cubes to ensure they get maximum crispiness.
Toss the potato cubes with 0.75 tsp of olive oil, sea salt, black pepper, and garlic powder directly on the baking sheet.
Roast the potatoes for 20-25 minutes, flipping halfway through, until they are golden brown and crispy on the edges.
While the potatoes roast, slice the chicken breast into thin strips or bite-sized pieces.
Dice the red bell pepper and red onion into uniform pieces.
Heat the remaining 0.75 tsp of olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and cook for 3-4 minutes until lightly browned.
Stir in the bell peppers, onions, and the chipotle peppers in adobo, breaking up the peppers with your spoon.
Sauté for another 5-6 minutes until the chicken is cooked through and the vegetables are tender-crisp.
Remove from heat and stir in the fresh lime juice to brighten the smoky flavors.
Serve the spicy chipotle chicken immediately alongside the crispy roasted potatoes.
