Perfect for holidays or when you just don't want to fuss over the stove-top. This recipe is so easy, with great results. Any type of cheese and sausage can be used. Also, other ingredients can be added, I usually add some shrooms and a dash of cayenne pepper, use your imagination. Do ahead: you can cook the sausage and onions the day before and refrigerate.
