Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Peel and dice the sweet potato into 1/2-inch cubes, then toss with 1 teaspoon of olive oil, paprika, and a pinch of salt.
Spread the sweet potatoes on the baking sheet and roast for 20-25 minutes until the edges are golden brown.
Season the chicken breast with garlic powder, salt, and black pepper on both sides.
Heat a grill pan or skillet over medium-high heat with the remaining 1 teaspoon of olive oil.
Grill the chicken for 5-7 minutes per side, or until the internal temperature reaches 165°F.
While the chicken rests, steam the broccoli florets over boiling water for 4-5 minutes until bright green and tender-crisp.
Plate the grilled chicken alongside the roasted sweet potatoes and steamed broccoli, finishing with an optional squeeze of fresh lemon.
