Preheat oven to 425°F; cut sausage into thirds, quarter potatoes, and chop peppers and onion into bite-sized chunks.
Toss all vegetables and sausage on a sheet pan with olive oil, smoked paprika, salt, and pepper.
Roast for 25 minutes, stirring halfway through, until potatoes are tender and sausage edges are browned.
Divide evenly among plates and serve.
