Bacon, Egg & Cheese Breakfast Sandwich - biscuit topped with a cheesy baked egg casserole and bacon. This is the ULTIMATE breakfast sandwich recipe. No scrambled eggs in these sandwiches. The biscuit is stuffed with a wonderful cheesy egg casserole. The egg casserole would be good on its own, but it is amazing on a biscuit with crispy bacon! Can assemble the biscuits ahead of time and reheat the next morning for a quick on-the-go breakfast. SO much better than the drive-thru!
