Preheat the oven to 400°F (200°C).

In a large bowl, combine the sweet potatoes, bell pepper, red onion, and broccoli.

Drizzle olive oil over the vegetables, then add garlic powder, paprika, salt, and black pepper. Toss to coat evenly.

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

Roast in the oven for 30 minutes or until the sweet potatoes are tender and lightly browned.

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