Preheat your oven to 425°F and line a baking sheet with parchment paper.
Dice the russet potato into small, uniform half-inch cubes to ensure even cooking.
In a bowl, toss the potato cubes with 1 teaspoon of olive oil, a pinch of sea salt, and black pepper.
Spread the potatoes on the baking sheet and roast for 20-25 minutes, flipping halfway through, until they are golden and crispy.
While potatoes roast, season the chicken breast on both sides with chipotle powder, garlic powder, salt, and pepper.
Heat the remaining 1 teaspoon of olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-6 minutes per side until cooked through and the spices form a fragrant crust.
During the last 4 minutes of chicken cooking, add the sliced red bell peppers and onions to the same skillet, sautéing until tender-crisp.
Slice the chicken into strips and serve over the bed of crispy roasted potatoes and sautéed vegetables.
Garnish with freshly chopped cilantro for a bright finish.
