In a large skillet, heat olive oil. Add onions and bell peppers to the skillet and cook 5 or so minutes, until starting to soften.
Add sweet potatoes, red potatoes and sausage and cook until sweet potatoes are starting to get soft, at least 10 minutes, and the sausage is browning on the outside (remember they are already cooked!).
Stir in apples and cook for 3-4 minutes, until apples are starting to soften but still have a little bit of bite to them.
Mix in salt, pepper and fresh rosemary.
