Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Dice the potato into 1/2-inch cubes and toss them in a bowl with 0.5 tbsp of olive oil, 0.25 tsp smoked paprika, and a pinch of sea salt.
Spread the potatoes in a single layer on the baking sheet and roast for 25-30 minutes, flipping halfway through, until they are golden-brown and crispy.
While the potatoes roast, slice the chicken breast into thin strips and toss in a bowl with the chipotle peppers in adobo, garlic powder, and the remaining smoked paprika.
Heat the remaining 0.5 tbsp of olive oil in a large skillet over medium-high heat.
Add the chicken strips to the skillet and sear for 5-6 minutes, stirring occasionally, until the chicken is cooked through and has a slight char.
Remove the chicken from the skillet and set aside; add the sliced bell peppers and red onion to the same skillet.
Sauté the vegetables for 4-5 minutes until they are tender-crisp and have picked up the smoky flavors from the pan.
Plate the spicy chicken alongside the crispy roasted potatoes and sautéed vegetables, finishing with the remaining sea salt and black pepper.
