Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Dice the russet potato into small cubes and toss them on the baking sheet with 0.5 tbsp olive oil, sea salt, and smoked paprika.
Roast the potatoes for 25-30 minutes, flipping halfway through, until they achieve a golden and satisfying crunch.
While the potatoes roast, coat the chicken breast evenly with the chipotle in adobo sauce, garlic powder, and black pepper.
Heat the remaining 0.5 tbsp olive oil in a non-stick skillet over medium-high heat.
Sear the chicken for approximately 6-7 minutes per side until the internal temperature reaches 165°F.
Add the sliced bell peppers to the skillet during the last 4 minutes of the chicken's cooking time, sautéing until tender-crisp.
Allow the chicken to rest for 5 minutes before slicing it into strips.
Plate the sliced chicken with the roasted potatoes and peppers, then garnish with fresh cilantro.
