INSTRUCTIONS
1. Preheat the oven to 375°F. Spray a 9 x 13 inch baking dish with nonstick seasoning.
2. Melt butter in a cast iron skillet over medium heat. Add the sausage and cook until lightly browned, about 5-10 minutes. Remove from the , then add onions. Cook, stirring occasionally, until golden brown, about 20 minutes. Remove from the heat.
3. Layer the potato slices evenly over the bottom of the dish, overlapping them; reserve enough of the potato slices to cover the top. Sprinkle the sausage meat over the potatoes. Arrange the sauteed onions evenly over the sausage, then the roasted peppers. Arrange the remaining potatoes over the peppers, drizzle with olive oil, sprinkle with the cheese, and season with salt and pepper.
4. Bake until the potatoes and cheese are slightly brown and you can easily insert a knife through the center, about 35-40 minutes.
