Preheat your oven to 400°F (200°C) and prepare a large baking sheet with parchment paper or aluminum foil for easy cleanup.

Slice the chicken sausage into ½-inch rounds and cut the zucchini, bell peppers, and red onion into bite-sized pieces, breaking the broccoli into small florets.

In a large mixing bowl, combine all ingredients and toss with olive oil, Italian seasoning, garlic powder, salt, and pepper.

Spread the sausage and veggie mixture on the prepared baking sheet in a single layer.

Roast for 25 to 30 minutes, tossing halfway through to ensure even cooking.

Once roasted, remove from oven, cool slightly, and serve warm, optionally over rice or quinoa.
