Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Wash and dice the russet potato into 1/2-inch cubes.
In a bowl, toss the potato cubes with half of the olive oil, half of the sea salt, and half of the black pepper.
Spread the potatoes in a single layer on the baking sheet and roast for 25-30 minutes until golden and crispy, flipping halfway through.
While the potatoes roast, slice the chicken breast into bite-sized strips.
Season the chicken with the remaining sea salt, black pepper, garlic powder, and smoked paprika.
Heat the remaining olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and sauté for 5-7 minutes until cooked through and slightly browned.
Stir in the minced chipotle peppers in adobo, coating the chicken thoroughly.
Add the fresh baby spinach to the skillet and toss for 1 minute until just wilted.
Serve the spicy chipotle chicken and spinach alongside the crispy roasted potatoes.
