The Verdict
It was true that both videos showed popular menu items being prepared in a McDonald’s restaurant. The Sausage Burrito and the “Scrambled Egg Sausage And Vegetable Mix” all came in one package.
As for the Big Breakfast, the McDonald’s website called the biscuits “warm biscuits,” rather than referring to them as fresh or made from scratch. The same went for its Hotcakes. Both appeared to be frozen and heated up in a microwave oven. As for the scrambled eggs, we previously published an exhaustive report on the ways McDonald’s cooks eggs on a per-menu-item basis. Breakfast sausage is absent from the Big Breakfast video, as @carlosarmendariz94 noted in the description.
