Yes! This recipe was actually inspired by a friend who told me she was attempting to make a keto breakfast hash using sausage. I didn't have sausage on hand and I was too excited about her idea to go out and get some, so I used the bacon I had in my fridge. To use sausage, cook it first as you would the bacon, crumbling it as it cooks. If you have a tablespoon or so of bacon drippings on hand, feel free to add that in too, for flavor.
