Preheat the oven to 400°F (200°C).
Toss the halved baby potatoes, bell pepper strips, and onion wedges with olive oil, garlic powder, Italian seasoning, salt, and pepper in a large bowl until everything is well coated.
Spread your seasoned veggies out on the sheet pan in an even layer. Take your sausages and nestle them amongst the veggies on the sheet pan.
Transfer the sheet pan to the oven and roast for about 35-45 minutes, or until the sausages are browned and the potatoes are tender. Halfway through the cooking time, turn the sausages and stir the vegetables for even browning.
Remove from the oven and let rest for a few minutes before serving. Garnish with fresh parsley or herbs of choice.
