Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Dice the potato into small 1/2-inch cubes to ensure they get extra crispy during roasting.
Toss the potato cubes with 0.5 tbsp of olive oil, 0.125 tsp of sea salt, and 0.125 tsp of black pepper on the baking sheet.
Roast the potatoes for 25-30 minutes, flipping halfway through, until they are golden brown and tender.
While potatoes roast, season the chicken breast evenly with chipotle powder, garlic powder, and the remaining salt and pepper.
Heat the remaining 0.5 tbsp of olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 6-8 minutes per side until the internal temperature reaches 165°F.
During the last 5 minutes of chicken cooking, add the sliced bell peppers to the skillet and sauté until just tender.
Remove from heat, drizzle the chicken and peppers with fresh lime juice, and serve immediately with the crispy potatoes.
