Preheat your oven to 425°F and line a large sheet pan with parchment paper or lightly spray with cooking oil.
In a large bowl, combine the halved potatoes, bell peppers, and onion wedges. Add the olive oil, smoked paprika, garlic powder, salt, and pepper. Toss everything until the veggies are evenly coated.
Spread the seasoned vegetables in a single layer on the prepared sheet pan. Add the sliced sausage pieces throughout.
Roast for 25 minutes, stirring halfway through, until the potatoes are tender and everything has nice caramelized edges.
Remove from oven, sprinkle with fresh parsley, and serve hot. Enjoy the compliments!
