Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Peel the sweet potato if desired and dice into 1/2-inch cubes, then cut the chicken breast into similar bite-sized pieces.
In a large mixing bowl, combine the chicken, sweet potato cubes, and broccoli florets.
Drizzle with olive oil and sprinkle with turmeric, garlic powder, sea salt, and black pepper, tossing thoroughly to coat every piece.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the pieces are not overcrowded to allow for proper roasting.
Roast in the oven for 20 to 25 minutes, tossing halfway through, until the chicken is cooked through and the sweet potatoes are tender and golden.
Remove from the oven and serve immediately for a clean, nutrient-dense meal.
