Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into 1-inch bite-sized pieces and dice the sweet potato into small 1/2-inch cubes so they cook evenly.
Chop the broccoli into small florets, slice the zucchini into half-moons, and dice the red bell pepper into 1-inch squares.
In a large mixing bowl, combine the chicken pieces, sweet potato, broccoli, bell pepper, and zucchini.
Drizzle the olive oil over the mixture and sprinkle with ground turmeric, garlic powder, sea salt, and black pepper.
Toss everything thoroughly with your hands or a large spoon until the chicken and vegetables are evenly coated in the golden spice mixture.
Spread the mixture in a single layer on the prepared baking sheet, making sure not to overcrowd the pan so the vegetables roast rather than steam.
Roast for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the vegetables are tender and lightly caramelized.
