McDonalds is introducing a new breakfast sandwich line, the Buttermilk Biscuit! It's pretty much the same choices as a McMuffin: sausage, sausage egg and cheese or bacon egg and cheese. It's guaranteed to be extra greasy, so if you're watching your calories, skip this one! This offer may vary by location, so you probably should confirm with your McD's if they are participating. Also there will probably be a long line up because people go crazy over free McDonalds!!
