Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
Wash the sweet potato and cut it into uniform wedges, about 1/2-inch thick.
In a large bowl, toss the sweet potato wedges with 0.5 tbsp of olive oil, half of the salt, pepper, garlic powder, and smoked paprika until evenly coated.
Spread the wedges in a single layer on the prepared baking sheet and roast for 20-25 minutes, flipping halfway through, until the edges are golden and crispy.
While the potatoes roast, season the chicken breast with the remaining salt, pepper, garlic powder, and smoked paprika.
Heat the remaining 0.5 tbsp of olive oil in a skillet over medium-high heat. Add the chicken and cook for 6-7 minutes per side, or until the internal temperature reaches 165°F.
Remove the chicken from the heat and let it rest for 3 minutes before slicing into strips.
Place the fresh baby spinach on a plate and top with the crispy sweet potato wedges and the sliced chicken breast.
