Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Peel and cube the sweet potato into half-inch pieces, then toss with half of the olive oil, smoked paprika, and a pinch of sea salt.
Spread the sweet potatoes on the baking sheet and roast for 20-25 minutes until the edges are golden and caramelized.
While the potatoes roast, season the chicken breast evenly with garlic powder, black pepper, and the remaining sea salt.
Heat the remaining olive oil in a non-stick skillet over medium-high heat and sear the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
In a small steamer basket or microwave-safe bowl, steam the broccoli florets for 3-4 minutes until they are bright green and tender-crisp.
Remove the chicken from the pan and let it rest for 3 minutes before slicing into thin strips.
Assemble the power bowl by placing the fresh baby spinach at the base, then topping with the roasted sweet potatoes, steamed broccoli, and sliced chicken.
