Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Dice the russet potato into small 0.5-inch cubes and toss them with 0.25 tablespoons of olive oil, sea salt, and garlic powder.
Spread the potatoes in a single layer on the baking sheet and roast for 25 minutes until golden and crispy.
While the potatoes roast, dice the chicken breast into bite-sized pieces and finely chop the red bell pepper.
Heat the remaining 0.25 tablespoons of olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-6 minutes until browned and cooked through.
Stir in the diced red bell pepper and the chipotle peppers in adobo sauce, cooking for an additional 3 minutes until the peppers soften.
Season the mixture with black pepper and a squeeze of fresh lime juice, then remove from heat.
Plate the crispy roasted potatoes and top them with the spicy chipotle chicken mixture.
Garnish with freshly chopped cilantro and serve immediately while hot.
