Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper for easy cleanup.

In a large mixing bowl, combine the sliced chicken sausage, bell peppers, zucchini, red onion, and broccoli.

Drizzle the olive oil over the mixture. Sprinkle with garlic powder, dried oregano, smoked paprika, salt, and black pepper.

Toss everything together until the sausage and vegetables are evenly coated with oil and spices.

Spread the mixture onto the prepared baking sheet in a single, even layer.

Place the pan in the oven and roast for 20 to 25 minutes. Halfway through the cooking time, use a spatula to toss the ingredients so they brown evenly.

Remove from the oven when the sausage is browned and the vegetables are tender and slightly charred at the edges.

Garnish with fresh parsley if desired and serve immediately.
