  3. bell peppers, a variety of colors.
  4. onion sliced lengthwise, so all the veggies are about the same size and shape.
  5. for seasoning and flavorings I used olive oil, salt, pepper and oregano. I mention in the recipe cart that you can use any seasoning you like

    1. Hi Bobbie, you use raw sausage. If using fully cooked sausage, all you need to do is re-heat it. In this case make and recipe and cook without the sausage, then in the last 10 minutes add your fully cooked sausage. Otherwise you’ll end up with overcooked dried sausage. Hope this helps!
