Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Dice the yellow potato into small, uniform half-inch cubes and place them in a bowl.
Toss the potatoes with 0.5 teaspoon of olive oil, sea salt, and black pepper until evenly coated.
Spread the potatoes on the baking sheet and roast for 20-25 minutes, flipping halfway through, until they are golden and crispy.
While the potatoes roast, slice the chicken breast into thin strips and toss with chipotle peppers, garlic powder, and lime juice.
Heat the remaining 1 teaspoon of olive oil in a large non-stick skillet over medium-high heat.
Add the sliced red onion and red bell pepper to the skillet, sautéing for 3-4 minutes until they begin to soften.
Add the seasoned chicken to the skillet and cook for 5-7 minutes, stirring occasionally, until the chicken is cooked through and slightly charred.
Plate the spicy chipotle chicken and peppers alongside the crispy roasted potatoes and serve immediately.
