Preheat the oven to 400°F (200°C).

In a large bowl, combine sweet potatoes, bell pepper, red onion, broccoli, olive oil, garlic powder, paprika, salt, and black pepper. Toss until vegetables are evenly coated.

Spread the mixture on a baking sheet in a single layer.

Roast in the preheated oven for 25-30 minutes, or until sweet potatoes are tender, stirring halfway through.

Remove from the oven and garnish with fresh parsley before serving.
