Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Dice the chicken breast, sweet potato, zucchini, and red bell pepper into uniform bite-sized pieces to ensure even cooking.
Place the chicken and all vegetables into a large mixing bowl, then drizzle with the extra virgin olive oil.
Sprinkle the garlic powder, onion powder, smoked paprika, sea salt, and black pepper over the mixture and toss thoroughly until everything is well coated.
Spread the chicken and vegetables in a single layer on the prepared baking sheet, making sure not to overcrowd the pan so they roast rather than steam.
Bake for 20 to 25 minutes, tossing the medley halfway through the cooking time, until the chicken is cooked through and the vegetables are tender with slightly charred edges.
Remove from the oven and serve immediately while warm and fragrant.
