Preheat your oven to 425°F (220°C).
Dice the red potatoes into 1/2-inch cubes and toss them with half of the olive oil, sea salt, and black pepper on a parchment-lined baking sheet.
Roast the potatoes for 20-25 minutes, flipping halfway through, until they are golden and crispy.
While potatoes roast, slice the chicken breast into thin strips and toss in a bowl with the chipotle peppers, garlic powder, and lime juice.
Heat the remaining olive oil in a large skillet over medium-high heat.
Add the sliced chicken, bell peppers, and red onion to the skillet.
Sauté for 7-9 minutes, stirring occasionally, until the chicken is cooked through and the vegetables are tender-crisp.
Serve the spicy chipotle chicken and vegetables immediately alongside the crispy roasted potatoes.
