Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Dice the Yukon gold potato into small half-inch cubes to ensure they get maximum crispiness during roasting.
Slice the bell peppers into thin strips and cut the chicken breast into bite-sized pieces.
In a large bowl, toss the potatoes, chicken, and peppers with avocado oil, chipotle powder, garlic powder, onion powder, salt, and pepper.
Spread the mixture in a single layer on the prepared baking sheet, ensuring nothing is overcrowded.
Roast for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the potatoes are golden and tender.
Squeeze fresh lime juice over the pan before serving to brighten all the smoky flavors.
