Add the onions, bell peppers, and diced potatoes to a baking sheet. Our potatoes are not peeled.
Pour the olive oil evenly over the vegetables and use tongs or a spatula to mix well until coated. If you want a low-calorie alternative, use olive oil spray.
Sprinkle the Italian Seasoning, Garlic Powder, Salt, and Black Pepper evenly over the vegetables.
Mix well until all vegetables are coated with the seasonings.
Spread the vegetables evenly on the baking sheet.
Add sausages on top of vegetables.
Bake in a preheated oven for 25 minutes, flip the sausage and vegetables about halfway through the cooking time.
Carefully remove from oven and cool for 5 minutes.
Serve.
Notes
The potatoes can be peeled if preferred; however, we do not peel ours.
