Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Dice the yellow potato into 1/2-inch cubes to ensure they roast evenly.
In a small bowl, toss the potato cubes with half of the olive oil, half of the sea salt, and half of the black pepper.
Spread the potatoes onto the prepared baking sheet and roast for 15 minutes.
While the potatoes are roasting, whisk together the chipotle peppers in adobo, lime juice, garlic powder, onion powder, and the remaining olive oil in a mixing bowl.
Cut the chicken breast into bite-sized pieces and toss them in the chipotle marinade until thoroughly coated.
Remove the baking sheet from the oven, push the potatoes to one side, and place the marinated chicken on the other side.
Return the pan to the oven and roast for another 15-18 minutes until the chicken is cooked through and the potatoes are golden and crispy.
Garnish the dish with freshly chopped cilantro and serve immediately.
