Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Peel and cube the sweet potato into 1/2-inch pieces, then toss them on the baking sheet with half of the olive oil, sea salt, and smoked paprika.
Roast the sweet potatoes for 20 minutes until they begin to soften and brown.
Add the broccoli florets to the baking sheet, drizzle with the remaining olive oil, and roast for an additional 10 to 12 minutes until the vegetables are tender.
While vegetables roast, season the chicken breast with garlic powder and black pepper.
Heat a non-stick skillet over medium-high heat and sear the chicken for 5-6 minutes per side until fully cooked.
In a small bowl, whisk together the honey and lemon juice, then pour it into the skillet over the chicken.
Simmer the sauce for 1-2 minutes until it thickens into a glossy glaze that coats the chicken.
Slice the chicken and serve it immediately alongside the roasted sweet potatoes and broccoli.
