Preheat your oven to 425°F (220°C).
Wash and dice the russet potato into 1/2-inch cubes.
In a bowl, toss the potatoes with 0.5 tablespoon of olive oil, garlic powder, and half of the sea salt.
Spread the potatoes in a single layer on a parchment-lined baking sheet and roast for 20-25 minutes until golden and crispy.
While potatoes roast, slice the chicken breast into thin strips and toss in a bowl with the chipotle peppers in adobo, remaining salt, and black pepper.
Heat the remaining 0.25 tablespoon of olive oil in a large skillet over medium-high heat.
Add the chicken strips, sliced red bell peppers, and red onions to the skillet.
Sauté for 6-8 minutes, stirring occasionally, until the chicken is cooked through and the vegetables are tender-crisp.
Plate the crispy roasted potatoes and top with the spicy chipotle chicken and pepper mixture.
Garnish with freshly chopped cilantro before serving.
