I've been making those for almost a year now. A couple suggestions if you really are going to try this:
Try some chopped up precooked chicken instead of bacon.
Add some jalapenos, mushrooms, onions or something like that.
Spread a base of cream cheese of shredded cheese to the breakfast sausage before adding any other ingredients.
If you have the means, cook it in a charcoal smoker grill instead of baking, you'll really appreciate the smoked flavor.
Like I said, I've made different variations of these "fatties" or "meat bombs" and no matter what ingredients you use, you really can't go wrong. Try a breakfast variation at some point, sausage, eggs, peppers, cheese and bacon.
