You can cook it with hot Italian sausages as in the directions below or you can make it with mild or sweet sausages. If you do, you may want to omit the peppers and add either a touch of honey, syrup, or brown sugar, and sliced tart apples . Either way, I think I'd keep the onions...but that's a personal choice. You can also add chili flakes or parsley or any herb/spice that suits your tastes. If you want to serve it over pasta, you can add a can or two of spaghetti sauce and slice the sausauges before frying. This recipe is so versatile, you can't go wrong.
