Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
Dice the russet potato into 1/2-inch cubes and toss them in a bowl with 1 teaspoon of olive oil, sea salt, black pepper, and garlic powder.
Spread the potatoes in a single layer on the baking sheet and roast for 25 minutes, flipping halfway through, until they are golden and crispy.
While the potatoes roast, whisk together the chipotle peppers in adobo and lime juice in a small bowl, then coat the chicken breast thoroughly with the mixture.
Heat the remaining 0.5 teaspoon of olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear for 6 to 7 minutes per side until the internal temperature reaches 165°F and the exterior has a nice char.
Remove the chicken to rest and add the sliced bell peppers to the same skillet, sautéing for 3 minutes until tender-crisp.
Serve the spicy chipotle chicken alongside the crispy potatoes and sautéed peppers for a balanced, flavorful meal.
