Make Cauliflower Tatoes and set aside. Cook turkey bacon in large skillet and set aside, keep the bacon grease in pan. Add ground beef to the same skillet and cook until browned. Add the seasonings and set aside. For the sauce: add butter in a pan and stir in the flour over low heat (can use the same pan as hamburger if you want more flavor). Cook until the flour has absorbed the butter and then add heavy cream and mustard. Cook until the sauce thickens. In a 9×13 baking dish place half of the sauce on the bottom of the dish. Spread the cauliflower tatoes as evenly as possible in the dish. Sprinkle half of the bag of cheese over the tatoes. Sprinkle on the ground beef. Pour the other half of the sauce over the beef. Sprinkle remaining cheddar cheese over the sauce and sprinkle the top with the bacon. Cover and bake on 350 degrees F for approximately 30 minutes. Allow to cool a bit before serving.
